Preparing and studying some physical properties of TiO2-PVA hybrid nanocomposite material for possible environmental applications

In the current work, a nano-hybrid composite material consisting of a polyvinyl alcohol polymer (PVA) was prepared as a matrix material in which nanoparticles of titanium oxide (TiO2) diffused at a rate of 20% as a weight percentage of the weight of the polymer by means of direct physical mixing to form a colloidal solution. The visual as well as the formality by scanning electron microscope (SEM), XRD, FTIR and UV-visible spectroscopy. The results of the XRD proved that the hybrid superposition is due to the presence of diffraction peaks belonging to the polymer as well as belonging to the titanium oxide. The optical properties were studied by means of the absorption spectrum of the nano-hybrid, and the direct energy gap was calculated, and it was approximately equal to 3.71 eV. The morphological characteristics, as shown by the transmission microscope images, were in the form of small spherical particles collected inside the polymer forming clusters.
