▎ 摘 要
This paper surveys the main exfoliation technologies to produce graphene, graphene oxide or reduced graphene oxide (rGO). The four main exfoliation technologies are known as mechanical exfoliation, liquid exfoliation, intercalation-exfoliation and oxidation-exfoliation-reduction. The qualities of graphene, graphite nanoplate, GO and rGO and the different process steps as well as the chemicals used in these four techniques are discussed in this paper. The review also includes the feasibility and sensitivity analysis of setting up exfoliation-based graphene factory, the market size of graphene and its feedstock i.e. graphite. Depending on the application of the graphene-enabled product, the respective technologies are located either in the trough of disillusionment, slope of enlightenment and plateau of productivity in the Gartner hype cycle.
