Gel polymer electrolyte based on poly(vinyl acetate) and poly(vinylidene fluoride) was prepared by solvent casting technique, in which the addition of plasticizers improves the conductivity of polymer membranes. The blend polymer electrolyte containing propylene carbonate (PC) exhibits the highest conductivity of 0.922 x 10(-2) S cm(-1) at room temperature because of the higher dielectric constant as compared to other plasticizers used in the present study. Material characterizations were done with the help of SEM and FT-IR techniques. The activation energy values were computed from 'log sigma-1/T' Arrhenius plots.
