摘要:
 摘要:以4,4’-二氨基二苯甲烷双马来酰亚胺(MBMI)为反应前驱体,3,3’-二烯丙基双酚A(BBA)和双酚A双烯丙基醚(BBE)为活性稀释剂,制备MBMIBBABBE(MBAE)聚合物基体。采用聚醚砜(PES)和酸化修饰的多壁碳纳米管(MWCNTs)为改性剂,通过原位聚合法制备MWCNTs/PESMBAE复合材料。研究复合材料的力学性能和介电性能。MWCNTs/PESMBAE复合材料的力学性能采用冲击强度和弯曲强度进行表征,结果表明:冲击强度和弯曲强度均随着MWCNTs含量的升高呈现先增大后减小的趋势,且在质量分数为002%时达到最高,分别提升了74%和53%。复合材料介电常数随MWCNTs含量的升高而降低,在低频区变化不大,当频率大于104Hz时下降幅度增大;介电损耗略有升高,在频率小于104Hz仍为千分位,可作为常规绝缘材料使用。
Abstract:
 Abstract:3,3’diallyl bisphenol A (BBA) and bisphenolA diallyl ether (BBE) were used as reactive diluent to toughen 4,4’diamino diphenyl methane bismaleimide (MBMI) and obtained MBMIBBABBE(MBAE) polymer matrix. Polyether sulfone (PES) and acidMWCNTs as modifier, MWCNTs/PESMBAE composite was prepared through insitu polymerization method. The mechanical properties of MWCNTs/PESMBAE composites were characterized by impact strength and flexural strength. The results showed that the impact strength and bending strength were both changed with the content of MWCNTs and showed a trend of first increases and then decreases, increased by 74% and 53%, respectively, when the content of acidMWCNTs was 002wt%. The change of dielectric constant for composite was not remarkable in low frequency area, when the frequency was more than 104Hz they decreased obviously. Dielectric loss of composites increased slightly, but they were less than 1×10-3, this composites could be used as a conventional insulation materials.
