Abstract

A method of manufacturing graphene includes preparing a support member, disposing a carbon layer on the support member, disposing a catalyst layer on the carbon layer, forming graphene on the catalyst layer, attaching a carrier to the graphene and forming a graphene-forming structure, separating the support member from the graphene-forming structure, and removing the catalyst layer.

Claims (13)

1. A method of manufacturing graphene, the method comprising:

preparing a support member;

disposing a carbon layer on the support member;

disposing a catalyst layer on the carbon layer;

forming graphene on the catalyst layer;

attaching a carrier to the graphene and forming a graphene-forming structure;

separating the support member from the graphene-forming structure;

removing the catalyst layer; and

wherein during the separating of the support member from the graphene-forming structure, the carbon layer is destroyed.

2. The method of claim 1 , wherein the support member comprises a metallic material or a ceramic material.

3. The method of claim 1 , wherein the carbon layer has a property of hydrophobicity.

4. The method of claim 1 , wherein the catalyst layer comprises copper.

5. The method of claim 1 , wherein the removing of the catalyst layer is performed by an etching process.
