摘要：

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 (epsilon(r)), imaginary (epsilon(i)) and electrical modulus for real (M-r) and imaginary (M-i) part was determined and plotted. The relaxation time, tau for these samples was determined and the plot shows that t decreases with conductivity of the complexes.
