Abstract
ZnO nanoparticles immobilized in polyvinylpyrrolidone PVP were prepared using solgel dipcoating technique with varying Zn2+/PVP ratios The films were characterized using atomic force microscopy xray photoelectron spectroscopy and Fourier transform infrared spectroscopy for chemical analysis The size and concentration of ZnO particles decreased as the Zn/PVP ratio decreased Under low Zn2+/PVP molar ratios ZnO particles were clearly well separated and capped in the PVP polymer matrix Electrical resistivity of 108 Ω cm was achieved under these deposition conditions
