Abstract: Aim of the research study of some physical properties of the hybrid films prepared with different percentages of TEOS/PVA (20%TEOS+80%PVA,50%TEOS +50%PVA, and 80%TEOS+20%PVA). The PVA80 (20%TEOS+80%PVA) It can be seen from these there is no variation in the transparency curve as they were in pure PVA. This means that silica has no effect on UV-Vis transparency wavelength when incorporated into the PVA. The Differential scanning calorimetric (DSC) was found that increases thermal stability of the hybrid films, an increase of ratio TEOS because of the thermal stability of silica. The last test moisture uptake, the moisture up take polyvinyl alcohol pure is more valuable than the hybrid film because the polymer hydrophilic.
