| 摘 要： | 以3-缩水甘油基氧丙基三甲氧基硅烷(EPTMS)为原料,合成得到了八官能团缩水甘油醚-多面体低聚倍半硅氧烷(简称POSS-EP)。采用4代树型端氨基聚酰胺-胺(PAMAM)作为POSS-EP和双酚A型环氧树脂(DGEBA)共混物的固化剂,制备了5个环氧基POSS/PAMAM杂化材料。通过动态差示扫描量热仪(DSC),研究了环氧和PAMAM的固化反应动力学。通过DSC、热重分析(TGA)、拉力和冲击测试,对环氧基POSS/PAMAM杂化材料的热性能和力学性能进行了研究。结果表明,该环氧基POSS/PAMAM杂化材料具有优良的热性能和力学性能。

| Abstract: | Glycidyl ether polyhedral oligomeric silsesquioxanes(POSS-EP) was prepared in high yield via hydrolysis and condensation of 3-glycidyloxypropyltrimethoxysilane(EPTMS).Through thermal copolymerization between G4 PAMAM dendrimers and blends of POSS-EP and bisphenol A epoxy resin(DGEBA),a series of epoxy-based POSS/PAMAM hybrid materials was obtained.The thermal copolymerization kinetics was investigated by means of dynamic differential scanning calorimetry(DSC).Thermal and mechanical properties of the hybrid materials were studied by means of DSC,thermogravimetric analysis(TGA),tensile test and impact test.The results reveal that these epoxy-based POSS/PAMAM hybrid materials exhibited excellent thermal properties and mechanical properties. |
