Abstract: 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-π stacking,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.
