The present invention is a method for producing graphene by the edge functionalization of graphite, the functionalized graphene having a functionalized organic material at the edge by preparing the organic material and graphite in the reaction medium containing the polymer phosphoric acid and a dehydrating agent, and then Functionalized graphene can be dispersed, centrifuged and reduced in a solvent, in particular heat treated, 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. |
