Abstract:
A method for industrially manufacturing large-size graphene comprises following steps: (1) mixing graphite and concentrated sulfuric acid to obtain a mixed liquid, and ultrasonically treating the mixed liquid to obtain an upper layer of graphene and a lower layer of concentrated sulfuric acid liquid under condition that a chemical intercalation and a mechanical stripping were performed simultaneously; (2) separating the upper layer of graphene and the lower layer of concentrated sulfuric acid liquid; (3) the graphene separated in the step (2) being washed with water, filtered, and dried to obtain a large-size graphene. The method has the advantages of good peeling effect, great graphene size, repeated use of sulfuric acid as an intercalating agent, environment-friendliness, resource saving and wide industrial application prospect.

Claim (Index 4):
The method for industrially manufacturing large-size graphene as recited in  claim 1 , wherein the mass concentration of the concentrated sulfuric acid is 75%\u02dc98%.
