Abstract
In this work, bio-degradable blended solid polymer electrolyte (BSPE) films made up of PVA:PS:(CH3COO)2Mg with different wt% ratios 50:50:00, 40:40:20, 35:35:30 and 30:30:40, prepared using solution casting technique at room temperature. The physical and chemical properties of the prepared BSPE films were done using XRD, FTIR, UV–vis spectroscopy, TGA and SEM techniques. The electrical properties were measured using impedance analyzer. The highest conductivity 6.28 × 10−4 S/cm and the highest energy band gap 3.52 eV observed for the BSPE film with ratio at room temperature was. The charge storage capability of the material was analysed using dielectric analysis. Cyclic voltammetry (CV) analysis of PVA:PS:(CH3COO)2Mg (35:35:30 wt%) BSPE film showed specific capacitance value as 2 F/g, energy density value as 8.68 W h kg-1 and power density value as 312 W kg-1 respectively.
