ORGANIC-INORGANIC HYBRID COMPOUND AND MANUFACTURING METHOD OF THE ORGANIC-INORGANIC HYBRID COMPOUND

摘要

PURPOSE: A method for preparing an organic-inorganic hybrid compound is provided to improve surface hardness, flexibility, and optical characteristic. CONSTITUTION: An inorganic-organic hybrid compound is denoted by chemical formula 1 and has acryl reactivity. A method for preparing the inorganic-organic hybrid compound comprises: a step of reacting a metal alkoxide and isocyanate; a step of reacting the obtained compound with acrylate compound; a step of performing co-hydrolysis and condensing the complex with metal alkoxide; a step of mixing the metal alkoxide complex of the obtained acryl group terminal with metal alkoxide; and a step of adding a catalyst and water for hydrolysis and condensing. The catalyst is hydrochloric acid, sulfuric acid, nitric acid, acetic acid, phosphoric acid, potassium hydroxide, or amine.
