Cornstarch-based biopolymer electrolyte doped with Na3PO4

Abstract

—In this work, polymer electrolytes have been
prepared by doping starch with Sodium Phosphate (Na3PO4
).
The incorporation of 25% Na3PO4
optimizes the room
temperature conductivity of the electrolyte at 7.27 x 10-6 Scm-1
.
The temperature dependence of conductivity for the electrolyte
is Arrhenius and the activation energy, Ea
, of 75% corn
starch-25% Na3PO4
electrolyte is 0.26eV. The dielectric studies
reveal the non-Debye nature of the electrolyte. The
complexation of Na3PO4 with the polymer host was studied
using Fourier transform infrared (FTIR) spectroscopy.
