摘要 制备出一种新型的由苯并噁嗪、环氧树脂和碳纳米管(MWNT)组成的复合材料。对MWNT进行了表面改性,降低了苯并噁嗪和环氧树脂固化的温度,增强了MWNT与苯并噁嗪/环氧树脂基体间的结合力。对该复合体系进行了分步固化的研究。动态力学分析与热重分析表明由于MWNT的加入使得复合材料的储能模量和耐热性增加。通过断面扫描用SEM观察了MWNT在复合材料中的分散情况。 A novel composite composed of benzoxazine, epoxy and multiwalled carbon nanotubes （MWNT） was prepared successfully. The surface modification of MWNT decreased the curing temperature of the system and improved the adhesion between MWNT, benzoxazine and epoxy. The step-curing of this system was researched. Dynamic mechanical analyses and Thermal gravity analyses indicated the storage modulus and heat resistance was improved. The dispersed MWNT inside composite was observed by SEM.
