Poly(vinyl alcohol)/carboxymethyl-chitosan (PVA/CMC) blend hydrogels
were synthesized by γ-radiolysis followed by freeze/thawing (FT). Previous,
the water-solubility of chitosan (CS) was obtained by γ-radiolytic acidic
degradation. CMC molecular weight characterization was performed by a
Zetasizer. The fluorescence measurements confirmed the presence of CMC
in the PVA/CMC blend hydrogels. In situ preparation of Ag nanoparticles
(AgNPs) in PVA/CMC blend hydrogel matrices has been performed
exposing hydrogels, swollen in AgNO3 solution, to γ-irradiation. The
mathematical models applied for determination swelling kinetics showed
that the initial concentrations of CMC and AgNPs directly have influence on
the swelling parameters of Ag-PVA/CMC nanocomposites. Diffusion
characteristics, determined by different diffusion models (Early Time (ET),
Late Time (LT) and Etters (E)) are less due to the presence of AgNPs.
