Effect of ZrO2 on conductivity of PVC-PMMA-LiBF4-DBP polymer electrolytes

Abstract

The preparation and characterization of composite polymer electrolytes of PVC-PMMA-LiBF4-DBP for different concentrations of ZrO2 have been investigated. FTIR studies indicate complex formation between the polymers, salt and plasticizer. The electrical conductivity values measured by a.c. impedance spectroscopy is found to depend upon the ZrO2 concentration. The temperature dependence of the conductivity of the polymer films seems to obey the VTF relation. The conductivity values are presented and results discussed.
