Keywords:Nanoparticle doped polymer, PolyVinyl Alcohol (PVA), Titanium dioxide (TiO2), Structure Properties, X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM)
AbstractIn this research, X-ray diffraction of the powder (PVA polymer, titanium dioxide with two parti-cle sizes) and (TiO2 (15.7 nm)/PVA and TiO2 (45.7 nm)/PVA) films have been studied,the amount of polymer is (0.5) g and (0.01)g from each particle sizes of nanoparticles will be used. Casting method is used to prepare homogeneous films on glass petri dishes. All parameters ac-counted for the X-ray diffraction; full width half maximum (FWHM), Miller indices (hkl), size of crystalline (D), Specific Surface Area (S) and Dislocation Density (δ). The nature of the structural of materials and films will be investigated. The XRD pattern of PVA polymer has semi-crystalline nature and the titanium dioxide with two particle sizes have crystalline structure; ana-tase type. While the mixture between these materials led to appearing some crystalline peaks into XRD pattern of PVA polymer
