The present invention is a method for producing graphene by the edge functionalization of graphite, the organic medium and graphite in the reaction medium containing methanesulphonic acid and phosphorus pentoxide, or the reaction medium containing trichloromethanesulphonic acid to the edge Functionalized graphene with functionalized organics can be prepared and then the functionalized graphene can be dispersed, centrifuged and reduced, in particular heat treated, in a solvent to obtain high purity, large area graphene and films. According to the present invention, graphene can be produced in large quantities at low cost while minimizing damage to graphite. |
