Conductivity and dielectric studies of methylcellulose/chitosan-NH 4CF3SO3 polymer electrolyte

Films of methyl cellulose (MC) /chitosan blends were prepared via solution casting technique and their properties with different amount of ammonium trilate, NH4CF3SO3 were compared. Measurements of conductivity as a function of frequency at room temperature on these films were carried out using HIOKI 3532-50 LCR Hi-Tester where the frequency was set between 50 Hz to 1 MHz. Samples having 40 wt% of NH4CF 3SO3 exhibit the highest room temperature conductivity of (4.99�4.18) x 10-6 Scm-1. Dielectric data were analyzed using complex permittivity and complex electrical modulus for the sample with the highest ionic conductivity. Copyright � 2014 Trans Tech Publications Ltd, Switzerland.
