Conductivity studies of a chitosan-based polymer electrolyte
چکیده انگلیسی

Ionic conductivity for the chitosan-NH4CF3SO3 system was conducted over a wide range of frequency and at temperatures between 298 and 313 K. Dielectric data were analyzed using complex permittivity ε* and complex electrical modulus M* for the sample with the highest ionic conductivity at various temperatures. The temperature-dependent conductivity data obeys Arrhenius relationship. Jonschers universal power law was used to analyze AC conductivity of the sample. Hopping frequency was determined and activation energy of hopping is almost equal to the activation energy of conduction. The AC conductivity master curve was obtained for the highest conducting sample when scaled vertically by σDC and horizontally by ωP.
