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 11):
A method for industrially manufacturing large-size graphene comprising following steps:\n (1) provide graphite and concentrated sulfuric acid to be mixed to obtain a mixed liquid, the mixed liquid is sonicated so that the chemical intercalation and the mechanical stripping are performed simultaneously, the mixed liquid is formed as an upper layer of graphene and a lower layer of concentrated sulfuric acid liquid, the concentrated sulfuric acid liquid contains unpeeled graphite; (2) dissociate the upper layer of graphene and the lower layer of concentrated sulfuric acid liquid; (3) the graphene dissociated in step (2) is washed with water, filtered, and dried to obtain a large-size graphene; (4) return the concentrated sulfuric acid liquid separated in step (2) to step (1) for recycling.
