| 摘 要： | 1 Results In this work, the ion conducting films of polyacrylonitrile (PAN) containing lithium triflate (LiCF3SO3) and sodium triflate (NaCF3SO3) were prepared by the solution casting technique. The ionic conductivity measurements were carried out using impedance spectroscopy. The room temperature conductivity for pure polyacrylonitrile film is 1.51×10-11 S·cm-1. The room temperature conductivity for the highest conducting film in the PAN-LiCF3SO3 and PAN-NaCF3SO3 systems is 1.51×10-5 and 7.99×10-6 S·cm-1, respectively. The conductivity-temperature studies were performed in the temperature range between 303 and 373 K. The results for the variation of the conductivity with temperature obeys the VTF law. The increase and decrease in the number of ions can be implied from the plots of dielectric constant, εr-frequency and dielectric loss, εi-frequency.
