Abstract
Blends of PMMA and PVC were synthesized using film cast and doped with Camphor Sulphonic Acid (CSA). In order that the mechanical properties do not deteriorate, plasticizers were not added. The amorphous nature of the doped samples was confirmed through XRD and ac electrical conductivity of these blends was studied as a function of frequency in the range 100 Hz to 1 MHz at eight different temperatures from 30 °C to100 °C. The nonlinearity observed indicates that the ion transport in polymer electrolyte is dependent on polymer segmental motion. The slight increase in conductivity with temperature was due to the hopping mechanism between the coordinating sites and the linear variation of conductivity with frequency for all the temperatures and the samples and was attributed to the polarization of electrodes.
