In recent years

graphene/polyaniline composites have attracted increasing attention of owing to the advantages of their extraordinary electrical

thermal

electrochemical and mechanical properties. We review the recent advances in the preparation of graphene/polyaniline composite

including in-situ polymerization

interfacial polymerization

self-assembly approach and solution mixing

etc. Graphene/polyaniline composites combine the advantages of graphene and PANI

and hence show various enhanced properties

which pave the way for their potential applications in many fields. The applications of graphene/polyaniline composite in supercapacitors

sensors

fuel cells and solar cells are discussed in detail.
