Abstract
The ionic conductivity, dielectric constant and X-ray diffraction (XRD) studies are reported on the solution casted film of [xPEO + (100-x) PMMA]:NH4ClO4 for x= 0-100 weight percent. The NH4ClO4 crystallizes out in the films with large amounts of polymethyl methacrylate (PMMA). However, addition of a small amount of PMMA in PEO: NH4ClO4 matrix enhances the ionic conductivity. The thermally activated conductivity variation is explained in terms of the electrolyte dissociation theory..
