Graphene laminate and method of preparing the same

1. A method of preparing a graphene laminate, the method comprising:

forming graphene having a planar structure on a graphitization catalyst film;

coating a surface of a substrate with a binder layer composition;

contacting the binder layer composition and the graphene;

curing the binder layer composition to form a binder layer; and

removing the graphitization catalyst film to prepare the graphene laminate,

wherein the graphene is formed in direct contact with the graphitization catalyst film,

wherein the binder layer composition comprises at least one of a room-temperature curable resin, a thermally curable resin, a hot-melt resin, or a low-pressure curable resin,

wherein the room-temperature curable resin comprises at least one of a cellulose ether, a glue, a vinylacetate, a nitrocellulose, a urethane, a cyanoacrylate, or a polyester acrylate,

wherein the thermally curable resin comprises at least one of a melamine, a phenol, or a resorcinol, wherein the hot-melt resin comprises at least one of a polyethylene, a vinylacetate copolymer, or a thermoplastic, and

wherein the thermoplastic comprises at least one of a polyurethane, a polyvinylchloride, a polystyrene, a polyamide, a polyethylene, a polyacetal, or a nylon.

2. The method of claim 1 , wherein the forming of the graphene comprises a vapor-phase method, a polymer method, or a liquid-phase method.

3. The method of claim 1 , wherein the contacting the binder layer composition and the graphene comprises contacting under a pressure.

4. The method of claim 1 , wherein the removing of the graphitization catalyst film comprises contacting the graphitization catalyst film with an acid.

5. The method of claim 1 , further comprising pressing the binder layer composition and the graphene by using a roller after contacting the binder layer composition and the graphene.
