Solid Ionic Conductors Based on Salted Chitosan - Fatty Acid Plasticizer Systems


Article Preview

Films of chitosan polymer doped with lithium acetate dihydrate (LiOAc.2H2O) and placticized with oleic acid (OA) and palmitic acid (PA) were prepared by the solution cast technique. The film containing 40.0 wt. % LiOAc and 10.0 wt. % of OA exhibit a room temperature conductivity of ~ 10-5 S cm-1 and the film containing 41.0 wt. % LiOAc and 7.7 wt. % of PA has conductivity ~ 10-6 S cm-1. The plot of ln(sT) versus 103/T for the highest conducting samples obey an Arrhenian relationship in the temperature range between 300 and 363 K implying that the conductivity is thermally assisted. FTIR spectroscopy and XRD techniques have been used for the complexation studies. The LiNiCoO2/chitosan-LiOAc-OA/MCMB electrochemical cell could be charged to a voltage of 4.2 V.
