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...
