▎ 摘  要

NOVELTY - The apparatus (1) has a tension control unit that is configured for depositing graphene while transferring the catalytic metal film in a roll-to-roll manner. An upper chamber (10) is provided with a supply roller for supplying the catalytic metal film to a deposition chamber (20). A winding roller is configured for winding the catalytic metal film on which graphene is deposited in the deposition chamber. A deposition chamber is connected to the lower portion of the upper chamber. A direction changing roller is configured for changing the direction of the catalytic metal film in the deposition chamber. A tension adjusting unit is configured for constantly adjusting tension acting on the catalytic metal film. USE - Double-sided deposition-type roll-to-roll graphene film manufacturing apparatus. ADVANTAGE - The apparatus prevents damage to the catalytic metal film on which graphene is deposited by providing a tension control unit, so that a constant tension can be maintained in the catalytic metal film, and prevents damage to the graphene by preventing the catalytic metal film from sagging by its own weight because the upper chamber and the deposition chamber are formed upright. The apparatus increases the productivity because heat inside the deposition chamber can be quickly cooled through the cooling tube of the deposition chamber. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the double-sided deposition-type roll-to-roll graphene film manufacturing apparatus.
