In This study synthesis of inorganic oxide material by a sol-gel technique through the formation of colloidal suspension (sol) and gelation of the sol into the gel enables incorporation of heat-sensitive active substances into the material during processing. Sol can be further processed into forms, such as monoliths(rod shape).The objectives of this study were to evaluate sol-gel derived silica gel as an implantable (monoliths). The structural properties of the prepared samples were studied, using X-ray diffraction (XRD) and Fourier transform infrared (FTIR), UV-VIS. Spectroscopy of xerogel...

The effect of water content in different ratio for water/Tetraethylorthosilicate (H2O/TEOS molar ratio) (R=2,3,4,and 5) was studied . R=2 was chosen as best ratio for adding organic polymers (PMMA&PVC) to prepare films from organic -inorganic materials and organic dye to prepare films of hybrid materials. Two silica forms were prepared. Silica xerogel rod was Prepared by molding method and silica thin film were prepared spin coating method. Organic-inorganic hybrids films were prepared with different mixing ratios(20%Polymer+80%TEOS,50%Polymer+50%TEOS,80%Polymer +20% TEOS). The of X-ray...
