摘要：
The Frequency dependant conductivity behavior of a plsticized polymer nanocomposite electrolytes based on polyethylene oxide + poly(ethyl methacrylate) + NaIO4 with zinc oxide as the filler and poly(ethylene glyool) as the plasticizer have been studied. The formation of nanocomposites and changes in the structural properties of the materials were investigated by X-ray diffraction (XRD). The electrical conductivity of pure and nano composite polymet blend films were studied in the temperature range 303-373 K. The electrical conductivity increased with increased with increasing nanopaticle concentraion and exhibited Arrhenius type dependent with temperature. The increase in conductivity with dopant concentration may be attributed to the formation of charge transfer complexes. Transport number data showed that the charge transport in this electrolyte system is predominately due to ions.
