  • Abstract

    The present investigation describes the preparation, structural characterization studies on three different systems namely; system-I ((PMMA + PVDF)v- (Mg(CF3SO3)2)1-y), where 1-y = 60, 50, 40, 30 and 20 mol% respectively, System - II ((PMMA + PVDF) y - (Mg(CF3SO3)2)1-y) z-(EC) 1-z, where 1-z = 25, 20, 15, 10 and 5 mol% respectively and System-III (((PMMA + PVDF) v - (Mg(CF3SO3)2)1-y) z - (EC) 1-z) b - (MgO) 1-b,where 1-b = 20, 15, 10 and 5 mol% respectively and these systems were prepared by solution-casting technique. In system-III the MgO nanofiller of 32 nm size prepared by wet chemical sol-gel method is added to arrive at nanocomposite solid polymer electrolyte systems in four different compositions namely 1-b = 20, 15, 10 and 5 mol% respectively. The synthesized MgO nanofiller size was confirmed by TEM study. Experimental techniques such as x-ray diffraction analysis, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and surface morphological studies involving optical microscopy have been employed to explore their structural properties.
