摘　　要：报道了以r 氨基丙基三乙氧基硅烷 ( 3 aminopropyltriethoxysilane ,NH2 (CH2 ) 3Si(OC2 H5) 3,KH550 ) ,r 氨基丙基二乙氧基甲基硅烷 ( 3 (diethoxymethylsily)propylamine,NH2 (CH2 ) 3Si(OC2 H5) 2 CH3,KH551 )及r 缩水甘油醚基三甲氧基硅烷 ( 3 glycidyloxypropytrimethoxysilane,H2 COCHCH2 O(OCH3) 3·Si(OCH3) 3,KH560 )为先驱体原料 ,经水解和聚合反应后 ,合成了具有一定弹性的有机 无机复合材料 .红外光谱表征了复合材料的结构特征 ;DTA/TG曲线表明 ,在 2 0 0℃以下 ,复合材料保持了很好的热稳定性 ;KH560 KH580 ,KH560 KH551复合材料的弹性模量约在 3 70～ 470MPa之间 .Organic-inorganic materials with certain elasticity were fabricated with the 3-aminopropyltriethoxysilane (KH550), 3-(diethoxymethylsily) propylamine (KH551) and 3-glycidyloxypropy-trimethoxysilane (KH560) as precursors. The material was measured and investigated with FT-IR spectra and DTA/TG. They keep thermal stability at 300 ℃. The elastic modulus of the obtained material was measured about 370～470 MPa.
