| titleOfInvention | Method for preparing graphene and composite material thereof |
| abstract | The invention discloses a method for preparing graphene and a composite material thereof, belonging to the technical field of graphene. The method adopts graphite oxide prepared by a Hummers method or improved Hummers method as a raw material and red aluminum as a reducing agent, and comprises the following steps of: firstly dispersing the graphite oxide prepared by the Hummers method or improved Hummers method in an organic solvent; and then reducing by use of the red aluminum, wherein different products are obtained by different washing processes; one product is graphene obtained by washing with aromatic hydrocarbons or esters, deionized water and diluted hydrochloric acid and drying; and the other product is a graphene/aluminum hydroxide composite material by directly washing with aromatic hydrocarbons or esters, deionized water and organic solvent an drying. According to the method disclosed by the invention, the red aluminum can be used as a reducing agent for reducing graphite oxide to obtain graphene, and the agglomeration of the prepared graphene is prevented by a functional graphite oxide mode; and meanwhile, the red aluminum can be used as a precursor of aluminum hydroxide to prepare graphene/aluminum hydroxide and graphene/aluminum oxide composite materials. |
