Abstract

Polymer electrolyte based on lithium triflate, LiCF3S03, and high molecular weight of chitosan was prepared using solution casting technique. The ionic conductivity for chitosan-LiCF3S03-Si02 samples were tested over wide range of frequency and temperatures between 303K and 343K. The conductivity is due to the mobile ions from the salt and pathways created during the reaction. The conductivity was calculated by using the bulk resistance, Rb obtained from the Cole-Cole plot through impedance spectroscopy which illustrating the variation of the real and imaginary impedance. Dielectric data were analyzed by using the dielectric constant, er, dielectric loss, E;, real electric moduli, Mr, tangent loss, tan 8, relaxation time and activation energy. The temperature dependence conductivity data obeys Arrhenius relationship.
