Proton conducting polymer electrolyte films based on chitosan complexed with adipic acid : an electrical and ftir study

Abstract

Solid Polymer Electrolyte (SPE) has a significant advantage over other type of polymer electrolyte. In order to enhance the conductivity of SPE, chitosan acetate doped adipic acid films were prepared by the solution cast technique. The characterizations of the samples were done by using Electrochemical Impedance Spectroscopy (EIS) over a wide range of frequency and temperature between 298 K and 353 K and Fourier Transform Infrared (FTIR) Spectroscopy. The highest ionic conductivity obtained for samples with 35 wt. % was 1.4 x 10-at room temperature. FTIR showed that complexation has occurred. FTIR exhibited shifts in amine and carbonyl bands at 1560 cm-9
