Method of post treating graphene and method of manufacturing graphene using the same

1. A method of post treating graphene, the method comprising:

providing graphene on a metal thin film;

providing a carrier on the graphene, the providing the carrier comprising:

supplying the carrier onto an outer surface of a coating roller; and

coating the supplied carrier onto the metal thin film by the coating roller without having the coating roller contact the graphene;

hardening the carrier; and

removing the metal thin film from the graphene,

wherein the coating roller is disposed to be separated by a predetermined distance from the graphene and configured to avoid applying pressure to the graphene.

2. The method of claim 1 , wherein the metal thin film comprises a panel-like shape, and

the post treating graphene is performed while a transporting unit is configured to transport the metal thin film.

3. The method of claim 1 , wherein the providing the carrier comprises printing or coating the carrier on the graphene.

5. A method of post treating graphene, the method comprising:

providing graphene on a metal thin film;

providing a carrier on the graphene;

hardening the carrier; and

removing the metal thin film from the graphene,

wherein the hardening the carrier comprises hardening the carrier using a hardening device comprising:

a hardening roller separated by a predetermined distance from the carrier and configured to emit heat or light to the carrier, the hardening roller configured to harden the carrier by rotating on a fixed location; and

a transporting roller.

6. A method of manufacturing graphene comprising:

transporting a metal thin film to a graphene forming apparatus;

providing graphene on the metal thin film;

providing a carrier on a first surface of the graphene, the providing the carrier comprising:

supplying the carrier onto an outer surface of a coating roller; and

coating the supplied carrier onto the metal thin film by the coating roller without having the coating roller contact the graphene;

hardening the carrier;

removing the metal thin film from the graphene; and

providing a protective film on a second surface of the graphene,

wherein the coating roller is disposed to be separated by a predetermined distance from the graphene and configured to avoid applying pressure to the graphene.

7. The method of claim 6 , wherein the post treating of graphene is performed using a reel-to-reel method.

8. The method of claim 6 , further comprising removing the carrier from the graphene provided with the protective film.

9. A graphene post-treated according to the method of claim 1 .

14. The method of claim 1 , wherein the carrier is coated on the graphene in response to the coating roller rotating.

15. The method of claim 14 , wherein the carrier is coated on the coating roller before the carrier is coated on the coating roller.

16. The method of claim 6 , wherein the carrier is coated on the graphene in response to the coating roller rotating.

17. The method of claim 16 , wherein the carrier is coated on the coating roller before the carrier is coated on the coating roller.
