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.
