摘要
近年来,利用石墨烯和聚合物复合以及通过纳米复合实现高分子材料高性能化成为聚合物复合材料新的研究热点和前沿。综述了纳米复合材料与高分子材料高性能化的研究现状,重点分析了石墨烯与聚合物界面之间的氢键、π-π堆栈、共价、配位、成核-结晶五个方面的作用机理;介绍了一些高性能纳米复合材料的主要性能;此外,高分子材料的失效研究和寿命预测对于材料的实际应用具有重要意义,以橡胶密封材料为例,重点讨论了其老化失效机理,以及添加剂、应力和油介质对其老化行为的影响,并指出了其今后的发展方向。
In recent years,various advanced polymer materials such as graphene/polymer nanocomposites and high performance polymer composites are attracting more and more attention.In this review,the importances of different interfacial interactions between graphene and polymer matrices including hydrogen bonding,π-πstacking,covalent bonding and coordination bonding for fabrication of graphene/polymer nanocomposites are systematically summarized.Further,how to achieve high-performance polymer nanocomposites through blending is also described.Besides,because failure mechanism and lifetime prediction of materials are very important for their application,the effects of additives,stress and lubricants on ageing behavior of rubber seals are investigated.The failure mechanism is proposed.
