Graphene solutions

摘要

Solubilizing process of graphite, comprises: reducing graphite by an alkali metal to obtain a graphite intercalation compound; and exposing the graphite intercalation compound to an aprotic polar solvent to give a reduced graphene solution, where the process is carried out under inert atmosphere. Independent claims are included for: (1) graphene obtained, in the step of evaporation of aprotic polar solvent, by the process; (2) reduced graphene solution obtained by the process; (3) use of graphene for the preparation of composite materials; and (4) use of a reduced graphene solution for deposition of graphene on a substrate.
