Commercially available reagents and starting materials (SigmaAldrich Chemical and Fisher Scientific) include the following: Tetraethylorthosilicate (TEOS), tin (IV) chloride, silicon (IV) chloride, sorbitan monooleate, 2-ethylhexanoic acid, calcium 2-ethylhexanoate and 1 M tetrabutylammonium fluoride in tetrahydrofuran were used as purchased without further purification.
The synthesis of alkoxysilane functionalized polymers from an anionic polymerization terminated with tetraethylorthosilicate at equimolar stoichiometry to polymeric lithium led to a polymer with a high coupling.
It was confirmed that a pure silica gel prepared by hydrolysis and condensation of Tetraethylorthosilicate
formed the apatite on the surface in simulated body fluid (6).
The formation of colloidal cadmium sulfide on introduction of sodium sulfide to tetraethylorthosilicate
(TEOS) gels impregnated with cadmium chloride precedes the aggregation of these colloid particles in the banded patterns characteristic of the so-called Liesegang phenomenon, or pattern precipitation.
Sol-gel reactions of tetraethylorthosilicate
were conducted within the nanophaseseparated morphology of Nafion[R] films to yield Nafion[R] / silicate nanocomposites.
Dual UV and moisture curable acrylated polyester, organic/inorganic hybrid coatings were prepared using a coupling agent and tetraethylorthosilicate
