| Abstract: | A highly active penta-coordinate silicon complex was prepared by the reaction of silica with ethylene glycol in the presence of potassium hydroxide.A double hydroxyl tetra-coordinate silicon was prepared by the reaction of this penta-coordinate silicon complex with 2-chloride ethanol.And the PMMA/ tetra-coordinate silicon hybrid materials was prepared by the reaction of the double hydroxyl tetra-coordinate silicon compound with MMA,KH-570,using BPO as initiator and hydrolyzed by acid catalysis through Sol-Gel.The structure of hybrid materials had been characterized by FT-IR and the rigidity,light transmittance,thermal-stability of hybrid materials also had been researched. |
| Keywords: | Sol-Gel tetra-coordinated silicon organic/inorganic hybrid material |
