Abstract

Ionic conducting polymers are of considerable interest recently, as they have wide range of applications including electrical storage devices. The present study is aimed at designing and characterizing one such ion conducting polymer complexed with various ionic salts. Here, solid polymer electrolyte films consisting of Poly methyl methacrylate (PMMA) complexed with various chloride salts (X) (X= KCl, NaCl, MgCl2) have been prepared by the solvent casting technique. Fourier transform infrared spectroscopy (FTIR) confirmed the formation of polymer-ion complex. The ionic conductivity studies have also been carried out using AC impedance spectroscopy technique. Interestingly, the maximum value of conductivity (8.268 X 10-8 S/cm) has been observed for PMMA/NaCl complex at ambient temperature.
