Zinc oxide–Polyvinyl alcohol (ZnO/PVA) nanocomposites doped with varying concentrations of nano ZnO were prepared by solution casting method. Zinc oxide nanoparticles were synthesized by simple chemical route. Structural, Optical and Spectroscopic properties of the prepared nanocomposites were studied by using Ultra Violet Visible Spectrophotometer (UV-Vis), X-ray diffraction (XRD), Fourier Transform Infra Red Spectrophotometer (FTIR) and SEM techniques. XRD and FTIR are used to determine the effect of the synthetic conditions and resulting processing on the material structure. XRD reveals the presence of nano ZnO with hexagonal wurtzite phase in the polymer matrix. The peaks in FTIR spectra of the prepared films show the interaction between nano ZnO and the PVA polymer. SEM shows homogenous dispersion of zinc oxide nanoparticles in the polyvinyl alcohol matrix. The optical properties of ZnO/PVA nanocomposites have been investigated.
