Organic-inorganic hybrid material compositions and polymer composites

A method for preparation of an organic-inorganic hybrid composition, comprising

• performing 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 base as a catalyst;
• said step of performing hydrolysis reactions and condensation reactions comprising obtaining a first intermediate, preparing a hydroxyl group-capping intermediate;
• performing a hydroxyl group-capping reaction with the first intermediate and the hydroxyl group-capping intermediate, and obtaining said organic-inorganic hybrid composition;
• said step of performing hydrolysis reactions and condensation reactions further comprising adding a metal doping agent, wherein said metal doping agent being one or more selected from the group consisting of metal alkoxides, metal halides, titanium acetate, zirconium acetate, titanium propionate, zirconium propionate and potassium titanium oxalate;
• said hydroxyl group-capping intermediate being prepared by reacting a hydroxyl reactable chemical with a hydroxyl functional polymerizable compound, and said first intermediate comprises a plurality of hydroxyl groups, and the plurality of hydroxyl groups are selected from the group consisting of Si—OH, Ti—OH, Zr—OH and combinations thereof;
• said hydroxyl reactable chemical being one or more selected from the group consisting of isocyanate and acyl halide;
• said polymerizable functional groups being one or more selected from the group consisting of acrylate, methacrylate, alkylene, arylalkylene, alkyne, cycloalkylene, cycloalkenylene, acyclic alkyl epoxide, cycloalkyl epoxide, mercaptam and cinnamate;
• and
• an atom ratio of metal atoms in said metal doping agent over silicon atoms in said functional organosilane or said combination of functional organosilanes being 1.0 :19.0 to 19.0:1.0.
