Abstract
A free standing transparent film of solid state polymer electrolyte based on PEMA/PVC+NaPF6 with different compositions of nano sized TiO2 in weight percent (x = 0, 1, 2, 7, 10, 15, 20) is synthesized by using standard solution cast technique. The homogeneous surface of above polymer composition is examined by FESEM. The microscopic interaction among polymer, salt and nano-ceramic filler has been analyzed by Fourier Transformed Infra-Red (FTIR) spectroscopy. The reduction of ion pair formation in polymeric separator is clearly observed on addition of nano-filler in the polymer salt complex film. Electrical conductivity has been recorded of the prepared polymeric separator which is of the order of ~1.5 × 10−5Scm−1 after addition of nano-filler (15 % wt/wt) which support the FTIR results. Electrochemical potential window has been observed of the order of ~6 V by the cyclic voltammetry results. The observed data of the prepared separator are at par with the desirable value for device application.
