Ayesha Kausar
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.
