摘要

Solid-polymer electrolytes (SPEs) in the form of poly(vinyl alcohol) (PVA) doped with various amounts (5, 10, and 15 wt %) of lithium perchlorate trihydrate (LiClO4 center dot 3H(2)O) and 2 wt % cesium copper oxide (Cs2CuO2) nanoparticles were fabricated by a solvent intercalation method. The obtained nanocomposites were evaluated for their chemical structure and microstructural and morphological behaviors via Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy methods, respectively. The obtained dielectric behaviors, alternating-current conductivity, dielectric modulus, and dielectric relaxation of the SPEs depended on the volume fraction of the electrolyte. Linear behavior of the current-voltage characteristics for all of the SPE films was observed with a slight deviation at a higher voltage. The thermal behaviors of the PVA-Cs2CuO2-LiClO4 films were evaluated by differential scanning calorimetry and thermogravimetric analysis. The refractive index, band-gap energy, and optical dispersion were examined with UV-visible spectroscopy. (C) 2017 Wiley Periodicals, Inc.
