Abstract

The review précises progress in the design, characteristics and potential of polyimide/graphene nanocomposite foam. The polyimide and graphene based foam architectures have been designed using two strategies, i.e., reinforcement of polyimide foam with graphene/graphene oxide nanofiller and the inclusion of preformed graphene, graphene oxide, reduced graphene oxide, or modified graphene foams in the polyimide matrix. In this regard, several advance approaches have been adopted to fabricate the polyimide/graphene nanocomposite foam. The polyimide/graphene nanocomposite foam possesses enhanced structural and physical properties. Consequently, the nanocomposite foam owns remarkable porosity, hierarchical nanostructure, electrical conductivity, thermal transportation, thermal stability, mechanical robustness and other superior features. The practical applications of polyimide/graphene nanocomposite foam have been experiential in the fields of sensing, radiation shielding, flame resistance and oil/water separation.

摘要

该评论详细介绍了聚酰亚胺/石墨烯纳米复合泡沫的设计、特性和潜力。聚酰亚胺和石墨烯基泡沫结构的设计使用两种策略，即用石墨烯/氧化石墨烯纳米填料增强聚酰亚胺泡沫，以及在聚酰亚胺基体中加入预制石墨烯、氧化石墨烯、还原氧化石墨烯或改性石墨烯泡沫。在这方面，已经采用了几种先进的方法来制造聚酰亚胺/石墨烯纳米复合泡沫。聚酰亚胺/石墨烯纳米复合泡沫具有增强的结构和物理特性。因此，纳米复合泡沫具有显着的孔隙率、纳米分级结构、导电性、热传输、热稳定性、机械强度等优越特性。
