GRAPHENE SOLUTIONS

摘要

The present invention relates to a method of solubilizing graphite and the applications thereof, in particular for the manufacture of composites and the purification of graphene. The method of the invention is characterized in that it comprises the following steps carried out in an inert atmosphere: a) reduction of the graphite by an alkali metal in order to result in a graphite intercalation compound; and b) exposure of said graphite intercalation compound to a polar aprotic solvent in order to result in a reduced graphene solution. The present invention relates in particular to graphene solutions and graphene planes obtained by said method, and also to uses of these graphene solutions and planes.
