The nanocomposite solid polymer electrolytes of Poly (ethylene oxide)/Polyvinylpyrrolidone doped with different concentrations (wt.%) of Zinc oxide nanoparticles (ZnO NPs) are prepared on quartz substrates using Spin-coat process. The Co-precipitation process is used to synthesize the ZnO NPs. The prepared nanocomposite polymer electrolytes were characterized by structural (XRD), morphological (SEM) and electrochemical (CV) studies. The spin-coating method is considered to be one of the most prominent due to the advantages of low cost and imperfection free uniform coating of resistant layers in the production of integrated circuits, surface coating and also acts as an intermediate insulator in different applications. The XRD analysis revealed the formation of nanostructures with (1 0 1) orientation in thin films which exhibits hexagonal Wartzite structure. All of the findings are correlated and discussed. The PEO/PVP/6 wt.% zinc oxide nanocomposite showed up to 500th cycles of reversible electrochemical response. The obtained results represent that nanocomposite solid polymer electrolytes based on ternaries are prominent materials for the use of transparent optoelectronic devices and solid-state batteries.
