dc.description.abstractZnO nanoparticles are prepared by the polymer precursor method using zinc oxide, polyethylene glycol and citric acid. Solution cast technique is used to prepare polymer electrolyte films having 70:30 weight ratio of the polyvinyl alcohol and lithium iodide salt incorporating 0, 1 and 2 wt% of ZnO nanoparticles. X-ray diffraction (XRD) pattern indicates that crystallinity of the polymer electrolyte films increases with the dispersal of ZnO nanoparticles in the polymer matrix. Vibrational changes in the nanocomposite polymer electrolyte films are shown by Fourier Transform Infra-Red (FTIR) Spectroscopy. The highest ionic conductivity is found to be ∼3_5×10−5 S/cm at room temperature for 70:30 PVA:LiI polymer electrolyte films. Ionic conductivity is found to be decreased with increasing amount of ZnO nanoparticles. Dielectric properties of the polymer electrolyte films are observed with varying ZnO nanoparticles in the polymer electrolyte films. Enhancement in the relaxation time and reduction in the dielectric loss are monitored with increase in the crystallinity of the polymer electrolyte films. © 2016 American Scientific Publishers All rights reserved.
