found that hydrophilicity increases as TEOS ratios increase when used a silica sol with tetraethylorthosilicate
(TEOS) and 3-methacryloxypropyltrimethoxysilane (TMSM) at different molar ratios.
(TEOS), triethoxyvinylsilane (VTOS), dibutyltin dilaurate (DBTDL), [alpha]-hexane, and ethanol were obtained as analytical reagents from Shanghai Chemical Reagent Company, China.
(TEOS) layers were applied on the glass substrate before coating with Ti[O.sub.2]-P25.
The pH of the synthesis gel strongly affects the hydrolysis-condensation rate of tetraethylorthosilicate
(TEOS) and therefore will affect the material geometry modifying the pore architecture, wall thickness and particle size, and the terminal groups located at the walls surface.
23 and 24).Termination of anionic styrene-butadiene copolymerization with tetraethylorthosilicate
(TEOS) yields an alkoxysilane functionalized polymer that has been shown to interact with silica in rubber stocks on a laboratory scale (ref.

film modified with protein to fabricate cholesterol biosensor," Talanta, 69(3)pp 700-705.
In another article, (11) a new class of nano Si[O.sub.2]/acrylic resin composite latex was synthesized by introducing nano Si[O.sub.2] particles formed in-situ hydrolysis of tetraethylorthosilicate
in emulsion polymerization.
The synthesized dimethyldiphenylsiloxane copolymers having different contents in diphenylsiloxane units (between 6.7-21.6 % moles) were mixed in different ratios with tetraethylorthosilicate
as crosslinker in presence of dibutyltindilaurate as catalyst.
The process uses 25 kg of liquid silicone (hexamethyldisilazane and tetraethylorthosilicate
) per metric ton of clean flake, or 2.5%.
This paper presents the methodology employed to consolidate stable sol and to make up thin ceramics films of Si[O.sub.2]-Zr[O.sub.2] and Si[O.sub.2] -Ti[O.sub.2] from Tetrabutoxytitanium (TBT), Tetraethylorthosilicate
(TEOS) and the Tetrabutoxyzirconium (TBZ) by using the method known as sol-gel.
In the present investigation porous silica gels with high surface areas were prepared from tetraethylorthosilicate
(TEOS) and Polyacrylic acid (PAA) of high molecular weight in acid media by a sol-gel method.
Gauze traps are used in this way when capturing tetraethylorthosilicate
