Abstract:
Nanocompistie polymer electrolytes of PVC+ZnO+Mg(ClO4)2 were synthesized by solution casting and studied using UV-visible spectroscopy and AC conductivity. The electrolytes had varying amounts of Mg(ClO4)2. Based on the findings of the UV visible spectroscopy, the sample with x=50 wt.% Mg(ClO4)2 had the best direct and indirect band gap values, suggesting that the interaction between the polymer, ZnO nanofiller, and Mg(ClO4)2 salt improved its optical properties. In terms of dielectric constant and ion dissociation, the sample with x=75 wt.% Mg(ClO4)2 performed the best out of all of the samples tested. polymer electrolyte with frequency-dependently high dielectric constant values is perfect for cutting-edge applications.

Key words: polymer electrolyte, solution casting, UV -visible spectroscopy, AC conductivity, dielectric constant.
