Abstract— Conducting solid phase polymer electrolyte (SPE) films were synthesized using solution casting method. The polyethylene oxide [PEO] complexed with an alkali salt sodium perchlorate [NaClO4] and nano-filler Nb2O5 with varying weight percentile [5%-15%] ratios. The complexation of NaClO4 salt with the polymer matrix PEO has been confirmed by XRD and surface morphology was understood by the SEM images and elemental composition was estimated by EDAX results. The AC conductivity measurements were done in the temperature range of 303K–343K using AC conductivity set up. The electrical conductivity shows an improvement and enhanced to fourth order. The conductivity in polymer electrolyte system is due to ions of alkaline salts and Nb2O5 nano-filler which are present in polymer matrix. Several electrical and dielectric characterizations were done for these films.
Keywords— Activation Energy, Conductivity, Dielectric properties, Nanocomposite Polymer Electrolyte [NCPE], solution cast technique.
