Abstract

Provided is a graphene synthesizing apparatus. The graphene synthesizing apparatus includes: a heater unit configured to apply heat onto a continuous catalyst metal film; a susceptor unit disposed between the catalyst metal film and the heater unit to uniformly provide the heat of the heater unit to the catalyst metal film; and a raw material supply unit configured to provide a raw material to a side of the catalyst metal film.

Claims (29)

1 . A graphene synthesizing apparatus comprising:

a heater unit configured to apply heat onto a continuous catalyst metal film;

a susceptor unit disposed between the catalyst metal film and the heater unit to uniformly provide the heat of the heater unit to the catalyst metal film; and

a raw material supply unit configured to provide a raw material to a side of the catalyst metal film.

2 . The graphene synthesizing apparatus of claim 1 , wherein the heater unit comprises:

a first heater unit disposed on a first surface of the catalyst metal film; and

a second heater unit disposed on a second surface of the catalyst metal film to face the first heater unit.

3 . The graphene synthesizing apparatus of claim 1 , wherein

the susceptor unit is provided in plurality, and

the plurality of susceptor units are disposed in a multistage structure and the catalyst metal film passes between the plurality of susceptor units.

4 . The graphene synthesizing apparatus of claim 1 , further comprising a raw material suction unit installed on another side of the catalyst metal film to face the raw material supply unit to suck the raw material.

5 . The graphene synthesizing apparatus of claim 1 , further comprising a tension maintaining roller configured to maintain the tension of the catalyst metal film while transferring the catalyst metal film.

6 . The graphene synthesizing apparatus of claim 1 , further comprising a chamber that forms an external appearance and in which the heater unit, the susceptor unit, and a portion of the raw material supply unit are installed.

7 . The graphene synthesizing apparatus of claim 6 , further comprising a vacuum pump installed at the chamber to control the internal pressure of the chamber.

8 . The graphene synthesizing apparatus of claim 6 , wherein the raw material supply unit comprises:

a raw material storage unit installed outside the chamber to store the raw material;

a raw material supply pipe connected to the raw material storage unit and installed to penetrate the chamber to flow the raw material therethrough; and

a raw material spray nozzle connected to the raw material supply pipe to spray the raw material onto the catalyst metal film.

9 . A graphene synthesizing method comprising:

emitting heat from a heater unit to heat a susceptor unit;

providing the heat of the heater unit uniformly through the susceptor unit to a catalyst metal film that is continuously provided; and

providing a raw material to a side of the catalyst metal film to synthesize graphene.

10 . The graphene synthesizing method of claim 9 , wherein the heater unit emits heat on both sides of the catalyst metal film.

11 . The graphene synthesizing method of claim 9 , wherein

the susceptor unit is provided in plurality and the plurality of susceptor units are disposed in a multistage structure, and

the catalyst metal film continuously passes between the plurality of susceptor units.

12 . The graphene synthesizing method of claim 9 , further comprising sucking the raw material on a side opposite to a side on which the raw material is supplied.

13 . The graphene synthesizing method of claim 9 , wherein the catalyst metal film is transferred with the tension thereof maintained.

14 . The graphene synthesizing method of claim 9 , wherein the graphene is synthesized in a vacuum environment.
