Patent number: 9428605Abstract: A method for the preparation of an organic-inorganic hybrid composition is performed through three major steps. In addition, a product is generated from this organic-inorganic hybrid composition. In step one, a series of hydrolysis reactions and condensation reactions with a functional organosilane or a combination of functional organosilanes, in presence of water as a reactant for hydrolysis and a suitable acid or a base as a catalyst is performed in order to obtain the first intermediate. In step two, a hydroxyl group-capping intermediate is prepared via reacting a hydroxyl reactable chemical with a hydroxyl functional polymerizable compound. In the third step, a hydroxyl group-capping reaction is conducted with the first intermediate and the hydroxyl group-capping intermediate, so as to obtain the organic-inorganic hybrid composition. It may further include a polymerization step to form an organic-inorganic hybrid polymer composition by UV irradiation or other approaches.Type: GrantFiled: November 8, 2013Date of Patent: August 30, 2016Assignee: NEO SITECH LLCInventors: Zhikai Wang, John Jun Chiao
