Characterisation of Polymer Electrolytes Based on High Molecular Weight PVC and BMIMCF_3SO_3

摘要

Polymer electrolyte films of poly(vinyl)chloride (PVC) as polymer host doped with ionic liquid l-butyl-3-methylimidazolium trifluoromethasulfonate (BMIMCF_3SO_3) were prepared by solution cast technique. Ionic conductivity was studied for 95 wt. % and 80 wt. % PVC by using Impedance Spectroscopy (IS). Arrhenius and Vogel-Tamman Fulcher (VTF) behavior were observed before and after Tg of the systems. Fourier Transform Infrared (FTIR) study confirmed that complexation occurred between PVC and BMIMCF_3SO_3.
