Abstract
Compositions comprising graphene/graphene oxide particulates synthesized under mild conditions, comprising reacting pristine graphene with hydrogen peroxide and a source of iron to oxidize the outer surface of the pristine graphene particulates in solution and yield graphene/graphene oxide particulates. Articles and composites incorporating the same are also disclosed.
Claims20
A composition comprising a plurality of graphene/graphene oxide particulates, said composition characterized macroscopically as a fluffy or fuzzy black powder or particulate, wherein each of said graphene/graphene oxide particulates comprises a pristine graphene core with a thin graphene oxide surface coating or shell, wherein said particulate comprises at least 85% carbon and up to about 15% oxygen.
