Effect of Frequency on AC Conductivity and Dielectric Constant on Composite Polymer Electrolyte

Polyvinyl alcohol (PVA), ammonium nitratre (NH4NO3) and nanofiller ZrO2 composite proton conducting polymer electrolyte with different concentration have been prepared by solution cast technique. The FTIR analysis comfirms the complex formation of polymer (PVA) with ammonium salt (NH4NO3). The ionic conductivity shows that 2 mole % dispersed nanofiller ZrO2 in (PVANH4NO3) composite polymer electrolyte has been maximum. The frequency dependence of ac conductivity and dielectric constant have been analysed of composite polymer electrolyte. And frequency dependent ac conductivity follows universal Jonschers Power law.
