Micro structural studies of PVA doped with metal oxide nanocomposites films

摘要: Nanostructured PVA polymer composites are of rapidly growing interest because their sized-coupled properties. The present article deals with both ZnO and WO3 embedded in a polyvinyl alcohol (PVA) matrix using solvent casting method. These films were characterized FTIR, XRD, SEM techniques. FTIR spectra the doped shows shift bands, which can be understood on basis intra/inter molecular hydrogen bonding adjacent OH group PVA. phase homogeneity morphology have been analyzed scanning electron microscope (SEM). crystal structure crystallinity nanocomposites studied by X-ray diffraction technique (XRD). Thus due to interaction dopant complex formation, structural repositioning takes place decreases.
