Abstract

PMMA-Poly Methyl Methacrylate, PVdF-Poly Vinylidene Fluoride and Silver Nitrate (AgNO3) based blend polymer electrolytes have been prepared by solution cast method. DMF (Dimethyl Farmamide) was used as a common solvent. These systems have been characterized by Scanning Electron Microscopy, Fourier Transform IR Spectroscopy and X-ray Diffraction for various ratios of prepared solid polymer electrolytes. DC ion conductivity has been studied for prepared electrolyte systems and the ionic conductivity of these systems showed Arrhenius behavior. It has been found that the electrolyte membrane's ionic conductivity rises with temperature. AC conductivity, electric modulus and dielectric studies have been investigated. The enhancement of conductivity was observed to be maximum for PMMA(70%):PVdF(30%):AgNO3(5%) (9.13 × 10–6 S/cm) and is attributed to decrease in crystallinity.
