  • Abstract

    Polyvinyl chloride (PVC) and polyethylene glycol (PEG) blend based polymer electrolytes were prepared with lithium perchlorate (LiClO4) as dopant salt. The nano-sized CuO particles were synthesized through sol-gel method and incorporated as filler. The electrolyte films were subjected to AC impedance analysis. The analysis reveals the strong influence of CuO particles on the conductivity profile. The film with 2 wt% of CuO exhibits higher conductivity of 4.013x10-6 S/cm at room temperature. The thermal stability of the membrane was ascertained through TGA analysis. The morphological study reveals the formation of dual-phase, an electrolyte rich-phase and polymer rich-phase.
