GRAPHENE REINFORCED MATERIALS AND RELATED METHODS OF MANUFACTURE

摘要

Graphene reinforced materials and related methods of manufacture are provided. The graphene reinforced materials include graphene sheet or scroll, graphene-polymer sheet or scroll, and graphene-carbon sheet or scroll, each having material properties that are attractive across a broad range of applications and industries. The graphene reinforced materials generally include monolayer or multilayer graphene that is synthesized by annealing a catalyst substrate within a CVD chamber, introducing a hydrocarbon gas as a carbon source with the CVD chamber to form a layer of graphene on the catalyst substrate, detaching the catalyst substrate from the layer of graphene, and rolling the layer of graphene onto itself to form a scroll, optionally with the addition of a polymer layer or carbonized layer on the graphene layer.

1. A method of forming a graphene scroll, the method comprising:
inserting a catalyst substrate into a chemical vapor deposition chamber; annealing the catalyst substrate in hydrogen gas within the chemical vapor deposition chamber; and exposing the annealed catalyst substrate to a reaction gas mixture including a hydrocarbon; synthesizing graphene from the reaction gas mixture following the exposure of the annealed catalyst substrate to the reaction gas mixture; detaching the annealed catalyst substrate from the synthesized graphene; and consolidating the synthesized graphene into a cylindrical multi-wall scroll having a spiral cross-section.
