In order to improve the performance of polyvinyl alcohol (PVA), the nanometer TiO2/PVA composite film prepared by solution casting, effects of nanotitanium dioxide (TiO2) PVA film. The structures, mechanical properties, and optical properties of the composite films were detected by infrared spectroscopy, TG, DSC, XRD. The results show that: nanoTiO2 fill added to the PVA matrix to improve the mechanical properties of PVA, thermal stability and UV shielding performance.

In this study, some optical properties were studied of the pure vinyl polyvinyl alcohol (PVA) nanopolymer (German origin). Under the influence of different temperatures and pressures of PVA. Where 25 samples were prepared for the purpose of conducting the research. Which studied the study of these samples was done by recording the absorbance and transmittance spectra of the wavelengths (200-900) nm. From them, absorbance, transmittance, reflectivity, absorption coefficient, refractive index, extinction coefficient, complex dielectric constant were calculated. At different temperatures (25,40, 80, 120, 160)°C. And with different pressures within the range (7.5,8,8.5,9,9.5) MPa. The results are that the permeability of the polymer (PVA) at different temperatures for each pressure decreases with increasing temperature, and that all other calculated optical properties increase with increasing temperature.
