The biopolymer blend electrolyte (BBE) films have been measured using Electrical Impedance Spectroscopy. The incorporation of 20 wt.% NHBr gives the optimum room temperature dc conductivity, dc of 2.12 x 10-5 Scm-1. Dielectric study shows dependence of BBE films on temperature, but independent to frequency. Based on the power law exponent result, CMC/CS-NHBr system can be represented by quantum mechanical tunnelling (QMT) model. Copyright@ International Science Community Association
