摘　　要：使用环氧氯丙烷对Kevlar纳米纤维(KNFs)进行改性,然后用环氧氯丙烷改性Kevlar纳米纤维(m-KNFs)分别对丁苯橡胶(SBR)和羧基丁腈橡胶(XNBR)及SBR/XNBR进行增强,并通过实验与分子模拟相结合的方式探究了3种纳米复合材料的热力学性能。结果表明,m-KNFs对SBR、XNBR和SBR/XNBR均有很好的增强效果,其中m-KNFs与XNBR基体之间的作用最强,m-KNFs可以有效改善XNBR与SBR的相容性。Poly(p-phenylene terephthalamide)was a high-performance polymer known by its trade name Kevlar[1].Kevlar nanofibers(KNFs)had reinforcing effect on rubber due to its high strength,high modulus,and excellent thermal and chemical stability[2].The poor interfacial adhesion between the Kevlar fibres and the matrix limited the overall performance of the composite to a large extent.
