AB  - Hydrogels with oligo(ethylene glycol) (OEG), oligo(propylene glycol) (OPG), and for the first time with combined OEG/OPG pendant chains within the methacrylate (MA) network, were synthesized and the swelling behavior, thermal properties, microstructure, and genotoxicity were investigated. Prior to hydrogel fabrication, an optimized method was developed for oligo(propylene glycol) methacrylate (OPGMA), i.e., oligomer with an LCST below a temperature at which synthesis occurs, indicating that proper preparation and tuning of reaction conditions were required. PEG6MA and PPG5MA homopolymers, as well as P(EG6/PG5)MA copolymer hydrogel, were produced by gamma radiation-induced polymerization and crosslinking of OEG and OPG monomers from the monomer-solvent mixture by using different water/ethanol composition as a solvent and by exposing the reaction mixture to various radiation doses. The combination of OEG and OPG pendant chains within the same network was advantageous in that it allowed an easy tuning of the phase transition temperature. Thus, the volume phase transition (VPT) at temperatures above 70 °C observed in the case of PEG6MA, and in the case of PPG5MA at temperatures below 15 °C, could easily be tuned close to physiological temperatures for P(EG6/PG5)MA hydrogel. Finally, all obtained thermoresponsive hydrogels showed non-genotoxic and non-cytotoxic properties, which indicate promising potential for biomedical applications.

AB  - Irrational and transcendental functions can often be seen in signal processing or physical phenomena analysis as consequences of fractional-order and distributed-order models that result in fractional or partial differential equations. In cases when finding solution in analytical form tends to be difficult or impossible, numerical calculations such as Haar wavelet operational matrix method can be used. In order to evaluate accuracy of the numerical inversion of irrational and transcendental Laplace transform using Haar wavelet operational matrix, a number inverse Laplace transforms are numerically solved and compared with the analytical solutions and solutions provided by Invlap and NILT algorithms.

AB  - In modern high-speed semiconductor electronics, there is a high-rate heating of components that is affected by very fast relaxation processes. The relaxation times of these processes should be known for thermal management of these devices. For almost half a century, photoacoustic techniques have been successfully developed and used to investigate physical semiconductor properties. In order to enable observation of fast relaxation processes, the model of pulse photoacoustic signal is proposed that includes influence of thermal relaxations. It is shown that these processes can be observed in a thin semiconductor layer by choosing the frequency of short pulse train and their duty cycle.

AB  - One of today's imperatives is the effective removal of pollutants from the biosphere, particularly from natural and wastewater sources. The removal of metal ions from solutions has long been a goal of numerous investigations, and hydrogels have been utilized as sorbent materials for this purpose. [1,2] This research was performed in order to create a new class of poly(oligo(propylene glycol methacrylate)/oligo(ethylene glycol methacrylate))/acid), abbreviated as p(OPGMA/OEGMA/acid), temperature-responsive copolymeric hydrogels and to analyze the influence of different acids on the volume phase transition temperature (VPTT) of the obtained hydrogels and on the efficiency of Mn+2 removal from the water. In this work, three acids were used: itaconic (IA), acrylic (AA), and methacrylate (MA), which were incorporated into the composition of the hydrogel in the monomer feed ratio OPGMA/OEGMA/acid of 95:2:3. Henceforth, the obtained hydrogels p(OPGMA/OEGMA/acid) were synthesized for the first time by γ-irradiation polymerization and crosslinking of monomers from a water/ethanol solution. The hydrogels were put through swelling analysis and testing as potential sorbents once the high level of gel content was confirmed. Taking into account the size of the metal ions, their concentration in the solution, and the porosity of the gel, the results show that hydrogels can be employed to remove manganese ions from solutions.

AB  - Polyolefins (POs) are currently the most widely used engineering plastics due to their
relatively low cost, durability, and ease of processing. A feature such as inertness makes
polyolefins suitable for applications such as food packaging and medical devices. For
the purpose of this study, polyethylene (PE) with good rigidity, hardness, impact
strength, environmental stress cracking resistance, and excellent processability, and
polypropylene (PP), with high fluidity and very good transparency, were selected
polyolefins [1,2]. Knowing that most of the polymer applications are strongly dependent
on the initial state of the products, i.e., their morphology, thermal properties, and
crystallinity, it is possible to obtain a great variety of morphologies and supermolecular
formations by varying different conditions in the preparation process, e.g. cooling
conditions during the crystallization process from the melt.
One of the aims of this work was to compare the results obtained for two different
methods of sample preparation, quenching, and slow cooling. Initial preparation was
performed for selected POs by rapid quenching in ice water and slow air cooling after
compression molding. Further, the prepared samples were characterized by SEM,
WAXD, FTIR, and mechanical measurements.
The obtained results indicated that PP is much more sensitive to the method of sample
preparation than PE, as well as that the initial preparation of samples plays a decisive
role in the final properties of materials for polymeric medical devices.

AB  - For many years now, thermally actuated hydrogels have been the ones most studied and employed in the field of polymeric biomaterials. The monomers, N-isopropyl acrylamide (NiPAM), and oligo(propylene glycol) methacrylate (OPGMA) were selected based on the sharp temperature response of their corresponding hydrogels in a known range of temperatures.1,2 This research was performed in order to create a new class of P(NiPAM/OPGMA) temperature-responsive hydrogels, and to analyze the influence of different content of monomers on the volume phase transition temperature (VPTT) of the obtained hydrogels. One of the objectives of this study was to provide insight into the effects of applied radiation dose on the swelling and mechanical properties of the hydrogels.  In further work, P(NiPAM/OPGMA) hydrogels were synthesized for the first time by γradiation crosslinking of monomers from water/ethanol solution. After the high sol-gel conversion was established, xerogels were subjected to swelling analysis and tested for the mechanism of water diffusion within the hydrogels. The obtained results indicated that new hydrogels based on NiPAM and OPGMA show promising potential for water treatment application due to the relatively high swelling degree of hydrogels and the ability to combine their VPTT close to annual river water temperatures in Serbia.

AB  - The paper presents a generalized model of the photothermal response of a polymer sample. The model is based on a linear non-Fourier heat conduction equation that considers thermal memory and complex heat capacity. The physical meaning of imaginary heat capacity is discussed from the point of view of non-equilibrium thermodynamics. The derived heat conduction equation introduces two additional dynamic properties of a medium to time-varying heat conduction: inertial and kinetic relaxation time. The influence of these relaxation times on photothermal response is analyzed. It is shown that the derived model could explain the measured photoacoustic response of different semi-crystalline polyethylenes (PEs). The obtained results show that photothermal techniques can be employed to estimate relaxation phenomena in polymeric materials when the frequency scale of the experiment is greater than the inverse value of any relaxation time. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Di(meth)acrylate (D(M)A) systems with pendant oligo(ethylene glycol) (OEG) chains are promising biomedical candidates. Homopolymeric P(OEG)D(M)A hydrogels have significant thermoresponsiveness demonstrated mainly at elevated temperatures which makes this class of materials unsuitable for bio-applications. Copolymerisation with less hydrophilic 2-hydroxyethyl methacrylate (HEMA) was performed in an effort to shift volume phase transition (VPT) closer to physiological temperatures and to widen their application as thermoresponsive materials. Various monomer-solvent mixtures, consisting of different mole ratios of OEGDMA and HEMA monomers (100/0, 50/50, 27.5/72.5, and 12.5/87.5) and water/ethanol as solvent, were exposed to gamma radiation up to 6, 12, 25, and 50 kGy. Furthermore, in an attempt to obtain multi- (thermo- and pH-) responsive hydrogels for biomedical applications new P(OEGDMA/HEMA/IA) terpolymers containing a small share (2.5, and 5 wt%) of itaconic acid (IA) were synthesised. The successful fabrication of the hydrogels was confirmed by gel measurements and FTIR spectroscopy. Swelling measurements indicated that obtained networks possessed tuneable thermal behaviour and swelling properties which could be significantly altered by hydrogel composition. The porous architecture was investigated using SEM, confirming swelling results. Cytotoxicity revealed relatively high cell viability for all hydrogels, indicating satisfactory in vitro biocompatibility. Therefore, new OEGDMA based hydrogels showed potential for biomedical applications.

AB  - Structural, conductive and dielectric properties of hybrid Polypyrrole (PPy)-TiO2 nanocomposite-coated polyamide fabric (PA-PPy/TiO2) synthesized by in-situ oxidative polymerization of pyrrole on the surface of polyamide in the presence of colloidal TiO2 NPs (d ~ 4.5 nm) have been studied. Raman spectra confirmed salt form of PPy in both neat PPy and PPy/TiO2-coated PA fabric and indicated its complete coverage. SEM/EDX analysis confirmed presence of TiO2 NPs and changes in granular structure of PPy deposited on the surface of PA fiber depending on the amount of TiO2 NPs. The PA-PPy/TiO2 nanocomposite sample with lowest content of TiO2 NPs (6.79 At.% Ti) showed highest conductivity (~10−6 S/cm) and dissipation factor (tan δ) in the entire frequency range. The lowest amount of TiO2 NPs in the PA-PPy/TiO2 nanocomposite induced two to four orders of magnitude higher tan δ value, compared to neat PPy covered PA fabric, depending on the frequency range. Frequency dependence of real (ϵ′) and imaginary part (ϵ″) of the complex permittivity for neat PA and PPy/TiO2-coated PA fabrics follow the trend of changes in dissipation factor for the same TiO2 NPs concentrations. The presence of TiO2 NPs could be exploited for tuning the conductive and dielectric properties of a conductive layer.

AB  - Oligo (ethylene glycol) oligo (propylene glycol) methacrylates (OEGOPGMA) with diferent numbers of ethylene glycol (EG) and propylene glycol (PG) units in backbone were used for the preparation of new thermoresponsive POEGOPGMA hydrogels; EG6PG3MA and EG3PG6MA monomers were used; and three diferent POEGOPGMA hydrogels (PEG6PG3MA, PEG3PG6MA and P(EG6PG3/EG3PG6) MA copolymer with equal mol% of previous two) were fabricated from mono‑ mer–solvent (OEGOPGMA–water/ethanol) mixture by gamma radiation. Charac‑ terisation of the hydrogels was conducted by swelling, UV–Vis, scanning electron microscope, diferential scanning calorimetry and in  vitro biocompatibility (cyto‑ compatibility and haemolytic activity) investigations. The modelling of drug release and difusion characteristics was tested using cephalexin drug. For the frst time, it was shown how to efectively tune the volume phase transition temperature (VPTT) values of the hydrogels by changing the ratio of more hydrophilic (EG) and more hydrophobic (PG) units in (EGPG) “block” pendant chains. The obtained hydrogels revealed the great potential for diferent biomedical applications not only due to the possibility to tune VPTT in the desired way but also due to the good biocompatibil‑ ity and controlled drug delivery within the target temperature range.

For the frst time, it was shown how to efectively tune the volume phase transition temperature (VPTT) values of the hydrogels by changing the ratio of more hydrophilic (EG) and more hydrophobic (PG) units in (EGPG) “block” pendant chains. The obtained hydrogels revealed the great potential for diferent biomedical applications not only due to the possibility to tune VPTT in the desired way but also due to the good biocompatibil‑ ity and controlled drug delivery within the target temperature range.",

AB  - Orientation and radiation processing of polymeric materials are the main steps in certain modern technologies and have extensive applications. The properties of such treated polymers can change significantly in time and under various exploitation conditions and therefore, investigation of some specific effects of aging and storage of these systems is of great importance, although the overall degradation behavior of iPP is well known. In this work, isotactic polypropylene (iPP) samples were oriented via solid-state stretching at elevated temperature (at 100°C, up to draw ratio λ=20). This was followed by gamma irradiation in the air (up to 700 kGy) and/or thermo-oxidative (TO) aging (in oxygen, at 100°C, up to 8 days) and/or storage (at room temperature, up to 3 years). As the iPP is very sensitive to orientation and degradation, microstructures were analyzed by optical (OM) and scanning electron microscopy (SEM). Wide-angle X-ray diffraction (WAXD) and differential scanning calorimetry (DSC) were used to monitor changes in structure and recrystallization. Considering the fact that at higher irradiation doses (>200 kGy), iPP starts to gel under the ambient conditions, gel measurements were employed to determine the yield of network formation induced by irradiation of stretched structures. Irradiation, TO degradation and storage, can induce substantial alternations of (di)electric properties which can be properly connected to the changes in microstructure and crystallinity; therefore, dielectric loss analysis was performed in a wide temperature range and polar groups that were introduced in apolar iPP by oxidation were considered as tracer groups. © 2021 Elsevier Ltd

AB  - This study provides a new insight into the relationships between absorption and adsorption processes that occur during the treatment of iPP in aqueous solutions of metal-chloride salts, as well as the impact of these processes on the electrical conductivity of this nonpolar polymer. The polypropylene films (0.5 mm) were exposed to three-day treatments in aqueous solutions of chlorine salts of some alkali and transition metals at temperatures of 22 °C and 80 °C. The treatments induced an increase in the electrical conductivity of iPP, up to 800%. DC conductivity is not directly proportional to the concentrations of metals in the treated films due to the complex relationships between diffusion and adsorption processes. The experiment was set up to simulate the real-world conditions and the study provides practical knowledge on the stability of the electrical conductivity of iPP under exposure to aqueous solutions. The influence of electric aging on the electrical conductivity of the treated films was also examined.

AB  - In order to investigate the resistance of poly-(l-lactide) (PLLA) to high-energy radiation, two varieties of samples with substantial differences in microstructure and crystallinity are prepared and exposed to the gamma radiation to various absorbed doses (up to 300 kGy). Since the PLLA morphology is sensitive to preparation conditions and radiation, surface microstructures are analyzed by scanning electronic microscopy. The chain scission degradation is followed using a gel permeation chromatography, while the additional characterization is conducted by differential scanning calorimetry, wide-angle X-ray diffraction method and IR spectroscopy. Presented results show that the quenched samples are more susceptible to radiation than initially high crystalline ones. Furthermore, the radiation leads to two considerably dissimilar recrystallization dynamics, connected with initial structural differences and the presence/absence of taut-tie chains. Radiation-induced increase in the crystallinity (more than 25% of initial value) for the quenched samples is noticeable at low radiation doses. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - The oligo(ethylene glycol) dimethacrylate (OEGDMA), one of the most commonly utilized crosslinking monomers, was used to tailor thermoresponsive POEGDMA hydrogels by varying the monomer/solvent feed ratio (from 10 to 100 wt% of monomer). For the first time, synthesis of different POEGDMA homopolymeric networks was performed by gamma radiation, and due to the expected thermoresponsiveness their temperature-dependent properties were extensively analysed. The sol-gel study was performed as the first step after radiation-induced synthesis. The swelling properties were investigated over the wide pH (2.2–9.0) and temperature (5–80 °C) range. Characterization of structure and properties was additionally conducted by SEM, DSC, FTIR, and UV–Vis spectroscopy. The results indicated that all POEGDMA hydrogels showed a high gel content, inverse thermoresponse and volume phase transition temperature (VPTT) with no respect to initial preparation. On the other hand, by altering the monomer/solvent ratio in the prepolymerisation mixture a large diversity in the microstructure, swelling capacity and VPTT was obtained. © 2019 Elsevier Ltd

AB  - Poly(l-lactide) (PLLA) is an extensively employed biodegradable semicrystalline polymer with usage from implantable medical devices and drug release matrices to environmentally friendly packaging materials. Since the morphology and crystallinity considerably determine the application field, PLLA samples with a large variation in crystallinity (going from below 20% to over 70%) were prepared by different procedures. Subsequent differences in morphology, crystallinity and thermal properties were followed by scanning electron microscopy (SEM), wide angle X-ray diffraction (WAXD) measurements and differential scanning calorimetry (DSC). The value of the enthalpy of melting of a perfectly (100%) crystalline PLLA was determined (ΔH f = 115.7 J/g). © 2019, © 2019 Taylor & Francis Group, LLC.

AB  - In this work, thermal diffusivity of crystalline high-density polyethylene samples of various thickness, and prepared using different procedures, was evaluated by transmission gas-microphone frequency photoacoustics. The samples composition analysis and their degree of crystallinity were determined from the wide-angle X-ray diffraction, which confirmed that high-density polyethylene samples, obtained by slow and fast cooling, were equivalent in composition but with different degrees of crystallinity. Structural analysis, performed by differential scanning calorimetry, demonstrated that all of the used samples had different levels of crystallinity, depending not only on the preparing procedure, but also on sample thickness. Therefore, in order to evaluate the samples thermal diffusivity, it was necessary to modify standard photoacoustic fitting procedures (based on the normalization of photoacoustic amplitude and phase characteristics on two thickness levels) for the interpretation of photoacoustic measurements. The calculated values of thermal diffusivity were in the range of the expected literature values. Besides that, the obtained results indicate the unexpected correlation between the values of thermal diffusivity and thermal conductivity with the degree of crystallinity of the investigated geometrically thin samples. The results indicate the necessity of additional investigation of energy transport in macromolecular systems, as well as the possible employment of the photoacoustic techniques in order to clarify its mechanism.

AB  - New hydrogels based on different oligo(alkylene glycol) methacrylate (OAGMA) with inverse thermoresponse and volume phase transition temperature (VPTT) were obtained and characterised in this paper. Synthesis was performed from monomer-solvent (OAGMA-water/ethanol) mixture by simultaneous radiation-induced polymerisation and crosslinking; three different OAGMA (EG(6)MA, EG(6)PG(3)MA, and PG(5)MA) were used. The main focus was made on PEG(6)PG(3)MA hydrogel based on ethylene glycol (EG) propylene glycol (PG) pendant chains with EG (6) and PG (3) block units, since in the case of POPGMA and POEGMA homopolymers (i.e. hydrogels with pure PG and EG pendant chains) the VPTTs were observed far below and far above the human body temperature, respectively. Characterisation of the hydrogels was performed by swelling, UV-Vis, FTIR, SEM, DSC and in vitro biocompatibility (cytocompatibility and haemolytic activity) investigations. Due to the possibility to combine VPTT close to human body temperature with good biocompatibility, new hydrogel based on EGPG block pendant chains showed promising potential for different biomedical applications.

The main focus was made on hydrogels based on EGxPGy pendant chains with different number of ethylene glycol and propylene glycol units in “block” backbone since in the case of POPGMA and POEGMA homopolimers (e.g. hydrogels with pure PG and EG pedant chains) the VPTTs were observed far below and far above the human body temperature, respectively. Characterisation of the hydrogels was performed by swelling, UV-Vis, FTIR, SEM, DSC and in vitro biocompatibility investigations.

AB  - Poly-L-lactide (PLLA) and hydroxyapatite/poly-L-lactide (HAp/PLLA) are two widely used biomaterials for three-dimensional scaffolds, drug release matrices and implantable medical devices for reparation of bone tissue; diversity in the initial preparation and filler content has a significant influence on different properties such as morphology and crystallinity, thus playing a considerable role in most of these applications. For this reason, PLLA and HAp/PLLA samples with a large difference in crystallinity (from below 20% to over 70%) and filler content (up to 86 wt% of HAp nanoparticles with an average diameter of 80 nm) were prepared and consequent dissimilarities in morphology, crystallinity and thermal properties were investigated by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD) measurements and Fourier transform infrared (FTIR) spectroscopy. Special attention was devoted to analyzing data obtained from thermal measurements. A three-phase model was employed in order to describe the heat capacity step decline in the nanocomposite; the evolution in different polymer fractions, the crystalline fraction and the mobile and rigid amorphous fractions, with filler content was determined.

Determination of gel fraction was performed as the first step after radiation induced synthesis. Tuning of the volume phase transition temperature (VPTT) of P(OPGMA/HEMA) copolymeric hydrogels was investigated by swelling study. Additional characterization of structure and properties was conducted by FTIR, DSC, and UV-Vis spectroscopy. All results indicate that new P(OPGMA/HEMA) copolymeric hydrogels have wide diversity in thermoresponsive properties which strongly depend on their composition. [GRAPHICS] .

Since the volume phase transition temperature (VPTT) of poly(oligo(propylene glycol) methacrylate) (POPGMA) homopolymer was below room temperature, it was necessary to tune the thermoresponsiveness and the VPTT to higher temperatures; radical copolymerisation of OPGMA with more hydrophilic and/or pH responsive monomers was used to adjust these values. A series of copolymeric hydrogels with different ratios of OPGMA, 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) was synthesised by gamma radiation. The swelling properties were preliminarily investigated over a wide pH (2.2-9.0) and temperature (4-80 degrees C) ranges. Additional characterization of their structure and properties was conducted by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The presented results revealed temperature/pH dual responsive P(OPGMA/IA) and P(OPGMA/HEMA/IA) copolymers with large diversity in swelling properties, as a result of the addition of OPGMA thermoresponsive units with a lower critical solution temperature (LCST) and IA pH responsive units. It was demonstrated that VPTT can be significantly shifted to higher (e. g. body) temperatures at higher pH values (pH = 4) by increasing the IA content in the hydrogel composition. Due to the possibility of making dual responsive copolymers in the manner explained in this paper, OPGMA based hydrogels show potential for different biomedical applications.
