▎ 摘  要

NOVELTY - Producing graphene, comprises (a) oxidizing graphite, and stirring to produce a selective-surface oxidized graphite plate, (b) reacting the selective-surface oxidized graphite plate with an aryl diazonium salt having hydrophilic functional group to produce graphitized plate grafted with hydrophilic functional group, and (c) stripping the grafted graphite plate using a rotating plate to produce selective-edge oxide monolayer or multilayer graphene. USE - The method is useful for producing graphene (claimed). ADVANTAGE - The method provides large-sized graphene having excellent aqueous solution dispersibility.
