摘要

为了研究双马来酰亚胺的增韧方法及其对耐热性的影响，首先利用超临界乙醇处理纳米Si02（SCE-Si02）；然后以4，4’-二氨基二苯甲烷双马来酰亚胺（MBMI）、3，3’-二烯丙基双酚A（BBA）、双酚A双烯丙基醚（BBE）为原料合成MBAE（MBMI—BBA—BBE）复合材料基体；最后加入SCE—Si02和PES制备了SCE-SiO2／PES／MBAE多相复合材料．SCE-SiO2的红外分析结果表明乙醇以分子形态吸附于纳米粒子表面，并改善了表面性能．通过SEM观察SCE-SiO2／PES／MBAE复合材料断面形貌，发现PES以微球状分散相的形式存在于基体中，断面形貌由脆性断裂向韧性断裂转变．材料的耐热性测试表明：SCE—SiO2与PES协同效应，有利于材料的耐热性．

Abstract

In order to research the method to toughen bismaleimide and analysis effect on thermal resistance

the nano-SiO2 was modified by supercritical ethanol （ SCE-SiO2 ） ; 4

4＇ -diamino diphenyl methane bismaleimide （MBMI）

3＇- diallyl bisphenol A （BBA） and bisphenol-A diallyl ether（BBE） were used to synthetise MBAE （MBMI-BBA-BBE） composite; SCE-SiO2/PES/MBAE composite was prepared from MBAE

PES and SCE-SiO2. The result of FT-IR showed that the surface of SiO2 was coated with ethanol molecule. The result of SEM showed that PES presented as disperse phase in MBAE matrix

the fracture transformed from brittle fracture to ductile fracture. Thermal resistance test showed there was synergistic effect between SCE-SiO2 and PES

and it was conducive to the thermal resistance of the material.
