FTIR and Ionic Conductivity Studies on PMMA based Gel Polymer Electrolytes

This article deals about the preparation and characterization of potassium, magnesium and ammonium ion conducting PMMA based gel polymer electrolytes. The gel polymer electrolytes were prepared by solution cast method. The formation polymer complex of ionic salts and PMMA were confirmed by FTIR. The ionic conductivities were measured by impedance spectroscopy at room temperature. It was found that the ionic conductivity of GPE is of the order of 10 -7 Scm -1 .
