Patent number: 9158197Abstract: A method of preparing an organic-inorganic hybrid material is described. A M(OR)x and an organically modified Si-alkoxide having a predetermined functional group are dissolved in a first solvent and a second solvent to form a first solution and a second solution, respectively. The first solution and the second solution are then mixed and heated. As a result, the M(OR)x reacts with the organically modified Si-alkoxide to form a functionalized organic-inorganic hybrid material. Furthermore, the solid content of the functionalized organic-inorganic hybrid material is increased by transferring the same into another solvent. Therefore, a thick hybrid film is fabricated by means of the transferred functionalized organic-inorganic hybrid material.Type: GrantFiled: September 9, 2008Date of Patent: October 13, 2015Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Guang-Way Jang, Ya-Hui Lin, I-Chia Tsai, Pei Tien, Yuung-Ching Sheen
