FTIR, conductivity and ionic transport study of chitosan doped adipic acid solid polymer electrolyte as proton conductor for battery application

Abstract

Film of adipic acid doped chitosan based polymer electrolyte was prepared by the technique of solution casting. The samples were characterized by using Fourier Transform Infrared Spectroscopy (FTIR), Electrochemical Impedance Spectroscopy (EIS) with temperature ranging 298 and 353 Kand transference number measurement. The highest conductivity at room temperature achieved is 1.4xl 0-for sample containing 35 wt. % of AA. FTIR showed that complexation has occurred. FTIR exhibited shifts in amine and carbonyl bands at 1560 cm -I and 1650 cm - I. Peak at 1689 cm-9 1 S cm-1 has shifted to 1680 cm-1 i
