ABSTRACT An organic/inorganic hybrid nanocomposite material was fabricated by blending epoxy resin with hydroxyl-terminated polybutadiene-based quaternary ammonium salt (HTPB-QAS) intercalated montmorillonite (MMT). The influence of HTPB-QAS-MMT content on the tribology and thermomechanical properties of the resulting epoxy-matrix nanocomposite was studied. The results show that suitable addition of HTPB-QAS-MMT can enhance the storage modulus and wear resistance, and decrease friction coefficient of epoxy polymer. The improvement of mechanical properties of HTPB-QAS-MMT modified epoxy can be attributed to the increased interaction between MMT, intercalant HTPB-QAS and epoxy polymer. Wear surface morphology analysis shows that the friction mechanism of 2E4MI cured sample is abrasive wear. The mechanical behaviours of DDM cured samples were also studied and were compared with those of 2E4MI cured ones.

含聚丁二烯基季铵盐嵌入蒙脱石纳米粘土的环氧基纳米复合材料的摩擦学和热机械性能

摘要 通过将环氧树脂与端羟基聚丁二烯基季铵盐 (HTPB-QAS) 插层蒙脱石 (MMT) 共混制备了一种有机/无机杂化纳米复合材料。研究了 HTPB-QAS-MMT 含量对所得环氧基质纳米复合材料的摩擦学和热机械性能的影响。结果表明，适当添加HTPB-QAS-MMT可以提高环氧聚合物的储能模量和耐磨性，降低摩擦系数。HTPB-QAS-MMT 改性环氧树脂机械性能的提高可归因于 MMT、嵌入剂 HTPB-QAS 和环氧聚合物之间的相互作用增加。磨损表面形貌分析表明，2E4MI固化试样的摩擦机理为磨粒磨损。
