Abstract
PVA/CdS nanocomposites were obtained by forming cadmium sulfide (CdS) nanoparticles at 1, 3, 5 and 10 cycles in the pores of polyvinyl alcohol (PVA) by layered chemical sorption of anions and cations from a solution of the corresponding salts. A comparative analysis of the temperature-frequency dependence of the electrical properties of the original and gamma-irradiated samples was carried out. It is shown that the reason for the observed changes in the electrical properties of the initial PVA and PVA/CdS nanocomposites under the action of gamma radiation is a change in the ratio of crosslinking, degradation, and oxidation processes occurring in the matrix and at the polymer-filler interface with an increase in the absorbed dose.
