摘要：

Films of hexanoyl chitosan-based polymer electrolyte were prepared by solution casting technique. LiCF3SO3, EC and Al2O3 were employed as the doping salt, plasticizer and filler, respectively. The ac conductivity of the electrolyte system under investigation has been studied in the frequency range from 100 Hz to 1 MHz over the temperature range from 273 K to 333 K. The exponent s in the Jonscher's universal power law equation sigma(omega)= sigma(dc) + A omega(s) was analyzed as a function of temperature. The analysis suggests that the conduction mechanism for the nanocomposite electrolyte system can be interpreted based on the correlated barrier hopping (CBH) model. The ac parameters such as the barrier height, W-M and cut-off hopping distance, R-min were calculated. The values of W-M and R-mm are found to decrease with increasing temperature in the same manner as the exponent s.
