Conductivity, dielectric behavior and FTIR studies of high molecular weight poly(vinylchloride)–lithium triflate polymer electrolytes

Thin films of high molecular weight polyvinyl chloride (PVC) with lithium triflate (LiCF3SO3) salt were prepared by solution casting method. The ionic conductivity and dielectric measurements were carried out on these films over a wide frequency regime at various temperatures. The conductivity–temperature plots were found to obey classical Arrhenius relationship. The dielectric behavior was analysed using dielectric permittivity and dielectric modulus of the samples. FTIR studies show some simple overlapping and shift in peaks between high molecular weight polyvinyl chloride (PVC) with lithium triflate (LiCF3SO3) salt in the polymer electrolyte complexes.
