A method for preparing an organic-inorganic hybrid material is provided to produce an organic-inorganic material for an optical waveguide device, which has good thermal and chemical safety and lower optical loss. A method for preparing an organic-inorganic hybrid material by the reaction of an inorganic non-metallic oxide and diol, comprises the steps of: sol-gel reacting (3-acryloxypropyl)trimethoxysilane, titanium methacrylate triisopropoxide and 4,4-(hexafluoroisopropylidene)diphenol in the presence of a catalyst for sol-gel reaction to prepare a precursor for an organic-inorganic hybrid; and adding a UV initiator to the precursor, spin-coating the admixture and irradiating the admixture with UV rays to be cross-linked. Preferably, the titanium methacrylate triisopropoxide is employed in an amount of 5mol%-20mol% based on the amount of 3-(acryloxypropyl)trimethoxysilane, and the catalyst is barium hydroxide monohydrate. |
