Electrical and ftir study of chitosan based polymer electrolytes doped glycolic acid

Abstract

The study of chitosan polymer behavior as a solid thin film electrolytes have attracted many researchers to involves into the conductivity exploration of chitosan polymer electrolytes. The prepared chitosan acetate doped glycolic acid (CA-GA) thin film was done in order to find the highest ionic conductivity of chitosan doped glycolic acid at different glycolic acid (GA) concentration and temperature. These thin films doped GA was made by using solution cast technique and analyzed by Fourier Transform Infrared Spectroscopy (FTIR) and Electrochemical Impedence Spectroscopy (EIS). FTIR analysis shows that the carbonyl (C=NHR) in pure chitosan (CS) spectrum has been shifted to 1637 cm ·1in the pure CA. The band at 900 cm·
