AB  - Bacterial cellulose (BC) is a highly pure polysaccharide biopolymer that can be produced by various bacterial genera. Even though BC lacks functional properties, its porosity, three-dimensional network, and high specific surface area make it a suitable carrier for functional composite materials. In the present study, BC-producing bacteria were isolated from kombucha beverage and identified using a molecular method. Two sets of the BC hydrogels were produced in static conditions after four and seven days. Afterwards, two different synthesis pathways were applied for BC functionalization. The first method implied the incorporation of previously synthesized HAp/TiO2 nanocomposite using an immersion technique, while the second method included the functionalization of BC during the synthesis of HAp/TiO2 nanocomposite in the reaction mixture. The primary goal was to find the best method to obtain the functionalized material. Physicochemical and microstructural properties were analyzed by SEM, EDS, FTIR, and XRD methods. Further properties were examined by tensile test and thermogravimetric analysis, and antimicrobial activity was assessed by a total plate count assay. The results showed that HAp/TiO2 was successfully incorporated into the produced BC hydrogels using both methods. The applied methods of incorporation influenced the differences in morphology, phase distribution, mechanical and thermal properties, and antimicrobial activity against Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), Proteus mirabilis (ATCC 12453), and Candida albicans (ATCC 10231). Composite material can be recommended for further development and application in environments that are suitable for diseases spreading.

AB  - The presented research focused on the metallization of polyester, cotton, and polyamide 6.6 fabrics using the silver conductive complex to allow electric conductivity through the fabric's surface and enhance the fabric's mechanical properties. The method used for the metallization of studied fabrics does not require the use of expensive toxic chemicals or electricity, making the process more economically acceptable. The signal attenuation was measured in frequency ranges of 1–4 and 5–12 GHz. After five cycles of metallization, the polyester fabric has higher EMI effectiveness, in a lower range was 45.44 and 57.25 dB. X-ray powder diffractometry (XRD) and infrared spectroscopy with Fourier transform infrared spectrophotometry (FT-IR) characterize the modified tissues. Scanning electron microscopy coupled with energy-dispersion spectroscopy (SEM-EDS) was used to determine layers' morphology and elemental composition. Also, the water and air permeability of modified textiles was determined.

AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol(PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained fromrice husk. The structural and morphological properties of the obtained particles, b-UPR, as well ascomposites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magneticresonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electronmicroscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanicalproperties of composites was supported by hardness modeling. Improvement of the tensile strengthof the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named“b-UPR/SiO2-V” composite, has been achieved with 88% increase. The thermal aging process appliedto the b-UPR/SiO2-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR).The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of atable top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, aswell as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainablecomposites that are chemically synthesized from renewable sources is important from the aspect ofpreserving the environment and existing resources as well as the extending their life cycle.

AB  - Electromagnetic interference (EMI) has become a widespread modern environmental pollutant. There is an essential need for practical and applicable materials for its attenuation. Therefore, the presented research has focused on metallization of carbon fabric using the silver conductive complex solution to enhance the surface conductivity and mechanical properties of the fabric. With this amplification and improving the mentioned characteristics, lightweight and flexible modified carbon fibers can be applied in many environments. The modification has been performed in three steps: the silver conductive complex synthesis, carbon fabric immersion into a silver complex solution, treating with temperature for silver deposition by annealing. The method used for the metallization of carbon fabrics surface does not require expensive and toxic chemicals or electricity, making the process more ecologically and economically acceptable. One of the advantages of using the method for surface modification is the possibility of usage for other materials, not only for textiles and foils. The examination of the surface structure, electrical, EMI shielding characteristics, and mechanical properties of carbon fabrics modified by silver deposition contributes to the determination of multifunctional properties of materials. Also, the dependence on the improvement of multispectral electromagnetic interference shielding effectiveness (EMI SE) characteristics and mechanical properties of materials on the number of cycles has been determined. The most effective material was carbon fabric modified by five cycles, and average attenuation at an L and S bands was 49.67 dB, and a part of C and full X band was 51.07 dB, caused by better coverage by silver particles, increased density and porosity of deposited layer. Increasing the number of silver deposition cycles improves the physical properties of the modified carbon fabrics, where after five cycles the highest maximum force has been measured (2.26 kN). The material's morphology was studied by scanning electron microscopy with Energy-Dispersive X-ray Spectroscopy. The crystallographic phases of sintered particles were determined by X-ray diffraction. The crystallographic phases of sintered particles were determined by X-ray diffraction.

AB  - Due to the increasing use and widespread of plastics, poly (ethylene terephthalate) (PET) and poly (vinyl chloride) (PVC) are becoming one of the major threats to the environment. The aim of this paper is obtaining plasticizers from recycled PET, and hot/cold mixing thereof with PVC to produce new materials. Plasticizer was obtained from PET using ethylene glycol (EG) in the presence of catalyst FASCAT 4100, followed by treatment with maleic anhydride and finally 2-ethylhexanol (2-EtHex). The obtained glycolysate and plasticizer, individually or mixtures thereof, were used for the production of polygranulates based on waste PVC in order to obtain an expanded mass of homogenized PVC with glycolysate/plasticizer. The abovementioned procedures and test results for the regranulates and products indicate that the proposed technology offers a solution to the problem of waste PET and PVC through transesterification in order to obtain plasticizer based on PET and EG, called 2-EtHex/MA/РG/PET/EG/MA/2-EtHex used in the processing of PVC waste and in regranulate. The obtained regranulates are further processed by injection molding or extrusion into commercial products such as slippers, footwear, boots, garden hoses, mats, floor mats, etc.

AB  - Recycling of polymer materials is a promising way of plastic waste reduction and production of compounds that reduce oil-based materials dependence. This paper represents synthesis of waste PET-based plasticizer obtained by esterification of PET depolymerization products (glycolisate) and levulinic (bio-renewable chemical). Depolymerization of the waste PET was performed using diethylene glycol. Morphological and structural analyses confirmed successful depolymerization of waste-PET, as well as esterification of the obtained product with levulinic acid. Good chemical resistance and mechanical properties, e.g. elongation at break of 65% and tensile strength of 50 MPa, of recycled PVC modified with synthesized waste-PET based plasticizer proved that depolymerization and modification of waste-PET represent one efficient solution for plastic waste recycling.

AB  - This paper presents the results of research on the application of nanomaterials on knitwear intended for camouflage protection. Polyester fibers that had already been dyed in camouflage shades (light green, beige green and dark green) were additionally treated with poly(vinyl butyral) (PVB) with or without incorporated nanoparticles of tungsten disulfide (WS2). This impregnation has proven to be successful in improving the camouflage characteristics of some other materials, like glass or cotton. For the prepared samples, the diffuse reflection, specular gloss and color coordinates of both treated samples and untreated samples were determined. Also, the samples wеre observed in the medium and long wavelength infrared spectrum using IR thermography. The obtained results indicated that there is a possibility of using this new impregnated knitwear in the wider area of the EMS.

AB  - In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical properties. Characterization of the newly synthesized nanofillers was performed using Fourier-transformation infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The purpose of this study was to analyze newly developed composite materials reinforced with silicate nanoparticles utilizing tensile testing and a full-field non-contact 3D Digital Image Correlation (DIC) method. Analysis of deformation and displacement fields gives precise material behavior during testing. Testing results allowed a more reliable assessment of the structural integrity of epoxy composite materials reinforced using different silicate nanofillers. It was concluded that the addition of 3% of dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite lead to the increasement of tensile strength up to 31.5%, 29.0%, 27.5%, and 23.5% in comparison with neat epoxy, respectively. In order to offer more trustworthy information about the viscoelastic behavior of neat epoxy and composites, a dynamic mechanical analysis (DMA) was also performed and rheological measurements of uncured epoxy matrix and epoxy suspensions were obtained.

AB  - This research considers a possibility to enhance the mechanical and spectrophotometric properties of a military camouflage cotton textile by applying a nano silver/poly(vinyl butyral), PVB, impregnation. Silver is known for its unique optical, electrical, thermal properties and antimicrobial activity[1]. PVB is chosen as a good impregnating matrix, being a thermoplastic elastomer with good adhesion behavior, resistant to wetting [2]. Impregnated fabric samples were examined regarding spectrophotometric properties and mechanical abrasion resistance. To achieve low visibility, besides being painted to match the colors of the environment, a surface must scatter light, so it should have a matte, low gloss coating [3, 4]. Diffuse reflectance and gloss are related, and from a spectral point of view, scattering properties are relevant for surface appearance [5]. Certain nanostructures may alter this feature.

AB  - In order to examine the possibility to improve its camouflage properties standard cotton fabric with camouflage print was impregnated with poly(vinyl butyral), PVB and fullerene-like nanoparticles of tungsten disulfide, PVB/IF-WS2. FTIR analysis excluded any possible chemical interaction of IF-WS2 with PVB and the fabric. The camouflage behavior of the impregnated fabric has been examined firstly in the VIS part of the spectrum. Diffuse reflection, specular gloss and color coordinates were measured for three different shades (black, brown and dark green). Thermal imaging was applied to examine the camouflage abilities of this impregnation in IR part of the spectrum. The obtained results show that PVB/IF-WS2 impregnation system induced enhacement of the materials camouflage properties, i.e. that IF-WS2 have a positive effect on spectrophotometric characteristics of the fabric.

AB  - Radar-absorbent materials, used in stealth technology for defense aircrafts, vehicles, satellites, etc. from radar detection, are commonly based on graphite or semiconductive particles embedded in a polymer matrix. In this study, we employed Co2+ ion-substitution to improve Vis-NIR reflectivity of hydroxyapatite (Ca10(PO4)6(OH)2, HAP) powder. HAP:Co with nominally 5 at.% of Co was prepared with hydrothermal processing of a precipitate. Synthesized powder was characterized by XRD, Raman and ATR-FTIR spectroscopy, FE-SEM and TEM. Thermal stability of HAP:Co powder was examined by simultaneous TG-DTA analyzer. To modify its optical properties and obtain powders with a varietty of color tone, the HAP:Co powder was calcined at 800, 1000, and 1100 °C, in an air atmosphere, for 1 hour. Afterward, the calcined particles were used to prepare composites with poly(vinyl butyral), (PVB); the concentration range was 1 wt.% of the HAP:Co in PVB. The composite coatings, in the form of thin films on glass, were prepared by the solvent-casting technique, using ethanol as a fast evaporating solvent. Firstly, the HAP:Co particles were dispersed in ethanol, then PVB was added (Mowital B30H) and dissolved. To evaporate the solvent before spectrophotometric measurements, the coatings on glass were dried at room temperature for 72 hours. To comprehend optical properties of the coatings, diffuse reflection, transmission, and color coordinates were determined. We found that calcined HAP:Co particles have potential to be used in the formulation of coatings for camouflage protection.

AB  - Nowadays, application of nanotechnologies is an emerging trend in defense technologies, as well as in all other fields. In previous years there has been an extensive research ongoing on the possibilities of application of nanotechnologies in order to enhance the armaments and military equipment. Among the application of nanofuels and nanomodifiers in energetic materials, active nanocatalysts of self-decontamination in CBRN protection, nanoreinforcements of composites and coatings, one group of nanomaterials stood out for its possible multidisciplinary applications and efficiency. Tungsten disulfide in the form of inorganic fullerene-like nanoparticles and inorganic nanotubes (IF-WS2 and INT-WS2), was previously known as a solid lubricant, extensively used by NASA, military, aerospace and automotive industry. WS2 comes in different shapes and forms and all of them are known for their good mechanical properties, but in these two nano-forms it has extraordinary impact, pressure and heat resistance, dry lubrication performance, and special conductive properties. In this paper a survey is presented of recent research of tungsten disulfide nanostructures potential use as in defense technologies, from dry lubrication, over reinforcement of polymers for binding systems, of composites for ballistic protection and aircraft construction, to camouflage protection coatings.
