Effect of Alumina Nanofiller and Diphenyl Phthalate Plasticizer on a Silver Ion Conducting Polyethylene Oxide Based Nanocomposite Solid Polymer Electrolyte

摘要

A novel silver ion conducting thin film nanocomposite solid polymer electrolyte (NSPE) has been prepared by blending poly(ethylene oxide) (PEO) as a polymer host with silver trifluoromethane sulfonate (AgCF3SO3) as a dopant ionic salt, aluminum oxide (Al2O3) as an inorganic nanofiller, and diphenyl phthalate (DPP) as a plasticizer using classical solvent casting technique and characterized by means of X-ray diffraction (XRD), electrical conductivity studies, field emission scanning electron microscopic (FESEM) and energy dispersive X-ray (EDX) analyses. Electrochemical cells have been fabricated and their discharge characteristics under dead load and at a constant load of 1 Ma"broken vertical bar have been studied at ambient temperature (298 K).
