“…This work has been published elsewhere [14]. Abraham et al [15] have prepared PAN polymer electrolyte films with EC and PC as plasticizers containing LiPF 6 /AsF 6 /LiN(SO 2 CF 3 ) 2 and they obtained the conductivity value in order of 10 −4 -10 −3 S cm −1 at room temperature. These results are in good agreement with the works that are described and reported by other researchers [16][17][18].…”

The conducting polymer electrolyte films consisting of polyacrylonitrile (PAN) as the host polymer, lithium triflate (LiCF 3 SO 3 ) and sodium triflate (NaCF 3 SO 3 ) as inorganic salts were prepared by the solution-cast technique. The pure PAN film was prepared as a reference. The ionic conductivity for the films is characterized using impedance spectroscopy. The room temperature conductivity for the PAN+26 wt.% LiCF 3 SO 3 film and the PAN+24 wt.% NaCF 3 SO 3 film is 3.04×10 −4 S cm −1 and 7.13×10 −4 S cm −1 , respectively. XRD studies show that the complexation that has occurred in the PAN containing salt films and complexes formed are amorphous. The FTIR spectra results confirmed the complexation has taken place between the salt and the polymer. These results correspond with surface morphology images obtained from SEM analysis. The conductivitytemperature dependence of the highest conducting film from PAN + LiCF 3 SO 3 and PAN + NaCF 3 SO 3 systems follows Arrhenius equation in the temperature range of 303 to 353 K. The PAN containing 24 wt.% LiCF 3 SO 3 film has a higher ionic conductivity and lower activation energy compared to the PAN containing 26 wt.% LiCF 3 SO 3 film. These results can be explained based on the Lewis acidity of the alkali ions, i.e., the interaction between Li + ion and the nitrogen atom of PAN is stronger than that of Na + ion.

Plasticized poly(vinyl chloride)/poly(ethyl methacrylate) PVC/PEMA-based blend polymer electrolyte films containing lithium perchlorate (LiClO 4 ) as a salt were prepared by solvent casting technique. The effects of the plasticization on structural, thermal and electrical properties of the plasticized polymer blend electrolytes were investigated. The changes in the structural and complex formation properties of the materials were studied by XRD and FTIR techniques. Dielectric relaxation studies of the polymer electrolyte have been undertaken, and the results are discussed. TG/DTA technique is used to study the thermal stability. Complex impedance analysis is used to calculate the bulk resistance of the complexes. The effect of different plasticizer on the structural and physical properties of polymer blend electrolyte is well correlated.

“…To improve the ionic conductivity, many studies have focused on the modifications of the PEO-based electrolyte system. Addition of nonaqueous organic solvent with low molecular weight into polymer matrix as a plasticizer has been proposed and extensively studied [4][5][6][7][8][9][10]. The polymer matrix acts as a host for a highly viscous liquid (plasticizer) which interpenetrates or swells the polymer.…”
