Abstract:
In this research, biopolymer electrolyte has been prepared by doping cornstarch with sodium iodide (NaI) using solution casting method. The incorporation of 25% NaI resulted in maximum conductivity of the electrolyte at 1.46 x 10-4 S cm-1. The enhancement of the electrical conductivity to 2.61 x 10-3 S cm-1 was achieved with further addition of graphene oxide (GO). The effect of GO on the electrolyte system were investigated by deploying electrical impedance spectroscopy (EIS) measurement at temperature of 298K-373K. Electrical conductivity as function of temperature have been investigated and revealed that the conductivity decreases as temperature increase. Dielectric studies were performed in order to study the ion mobility in the electrolyte system.
