|Abstract:||Plasticized polymer electrolyte films, of three different compositions containing poly (methyl methacrylate) (PMMA) as polymer, propylene carbonate (PC) as plasticizer, and potassium iodide and iodine as salt, have been prepared by solvent casting technique. The PMMA/PC mole ratio has been fixed as 25:75. Of the three, the sample with the polymer salt composition of 25:2.5:0.25 (PPE1) shows the highest ionic conductivity of ~ 8.177 × 10-4 S/cm at room temperature. Amorphous nature, complexation and surface morphology of the polymer electrolytes have been confirmed by X-ray diffraction analysis, Fourier transform infrared analysis and scanning electron microscopy, while the electrochemical behaviour of PPE has been studied by cyclic voltammetry.|
