Lauroyl-chitosan/poly(methylmethacrylate)-lithium trifluorosulfonate (LiCF3SO3) polymer electrolytes has been prepared by the solution casting method. Ionic conductivity analysis was conducted over a wide range of frequency between 50 Hz-1 MHz using impedance spectroscopy to evaluate the dielectric properties and conductivity of the sample. Sample with 30 wt% of LiCF3SO3 showed the highest conductivity of 7.59 ± 3.64 x 10-4 Scm-1 at room temperature. Complex permittivity for real (εr), imaginary (εi) and electrical modulus for real (Mr) and imaginary (Mi) part was determined and plotted. The relaxation time, τ for these samples was determined and the plot shows that τ decreases with conductivity of the complexes.References
