Abstract
A graphene base, including: graphene; and a substrate, wherein the graphene is formed directly on at least one surface of the substrate, and at least about 90 percent of an area of the surface of the substrate does not have a graphene wrinkle.
Claims16
A method of preparing a graphene base, the method comprising:
- disposing a carbon-based material on at least one surface of a substrate;
- disposing a graphitization catalyst layer on the carbon-based material in a way such that the carbon-based material is disposed between the graphitization catalyst layer and the substance;
- and
- forming graphene by thermally treating the substrate, on which the carbon-based material and the graphitization catalyst layer are formed, under an inert atmosphere or a reducing atmosphere.
