Abstract

In this study, investigating the effects due to doping of zinc oxide (ZnO) nanofillers in polymer composite electrolyte films and examine the electrical and structural properties of solution matrix. Wherecombination of Poly vinyl alcohol (PVA) and Potassium iodide (KI) were selectedas polymer electrolyte and ZnO was synthesized and used asnano-filler.  In order to investigate the effects of nanofiller ZnO on the performance of PVA-KI films, varying different concentrations of ZnO nanoparticles are incorporated into the films in order to study their conductivity, dielectric behavior and optical transmission. Adding ZnO nanofillers to PVA-KI solution matrix significantly increases its ionic conductivity, as shown by electrical measurements. The conductivity increases with the increasing concentration of ZnO up to an optimal doping level, beyond which it decreases, due to more agglomeration of nanoparticles. A notable dependence between the dielectric constant and loss tangent of the films is also observed with increases in ZnO content, as a result of improved charge transport and polarization effects.

Keywords: Polymer electrolyte films, PVA-KI films, ZnO nanoparticles, Polarization effects
