eng	Effect of Zinc oxide nanoparticles loading on electrically conductive properties of Polyvinyl Alcohol-Polyaniline polymer films	Polyvinyl alcohol-Polyaniline composite films with different amounts of zinc oxide (ZnO) were prepared by in situ polymerization followed by film casting and drying. The polyvinyl alcohol (PVA) and Polyaniline (PANI) concentration was kept constant with varying ZnO concentration (0.2%, 0.4%, 0.6% and 1%). The samples, ZnO and PPZ, were characterized by X-Ray Diffractometry (XRD), Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Thermo-Gravimetric Analyzer (TGA), UV-Visible spectroscopy and Impedance analyzer techniques. XRD patterns confirmed the formation of ZnO nanoparticles and PPZ films. The FESEM results show morphology of the ZnO and PPZ films. The FTIR results show the peaks corresponding to the formation of PPZ films. The DSC and TGA spectra predict the thermal characteristics of the PPZ films. The UV-Vis spectra show the absorption peaks of PPZ. The electrical conductivity plots obtained from the impedance analyzer between frequency ranges of 10 Hz to 100 kHz show that the increase in concentration and temperature of the samples show the higher conductivity of the PPZ films. For 1% ZnO concentration at 150 ˚C, the AC conductivity of PPZ1 is 20.06 S/m, which is very high. Such conductivity behaviour samples render the applicability of the PPZ films.
