摘要

Biodegradable polymer electrolyte systems of Rice Starch-Lithium Iodide (RS-LiI) films wereprepared using solution casting method. At room temperature, RS:LiI film with ratio of 65 wt.%:35 wt.% demonstrates the highest ionic conductivity of 4.6810 S cm . Temperature-dependence ionicconductivity study follows Arrhenius model and using related plot, activation energy for highestconducting composition is 0.41 eV. The ac conductivity of each film is increased with increase in LiI+ content. Dielectric properties of mobility, diffusion coefficient, number density of mobile ions (Li )and number of transitions per unit time were determined using Rice and Roth model. At higherconductivity, dielectric parameters were increased due to more mobile ions. The structure of polymerelectrolytes was characterized by FTIR spectroscopy. Infrared spectra of compositions exhibited bandshifts at different salt ratios. These shifts confirm complexation between host and salt.
