摘要

The cutting device comprises a reception (10) to receive graphene (19) for cutting, a cutting element (12) loaded with a catalytically active material in an area of a cutting edge, a displacement device to displace the reception and the cutting element with the cutting edge relative to each other, and a heating device (14) to provide heat energy for catalytic reaction of graphene in the area of a cutting path under participation of the active material. The active material is disposed on a surface of the cutting edge. The cutting edge is made of the active material in a section-wise manner. The cutting device comprises a reception (10) to receive graphene (19) for cutting, a cutting element (12) loaded with a catalytically active material in an area of a cutting edge, a displacement device to displace the reception and the cutting element with the cutting edge relative to each other, and a heating device (14) to provide heat energy for catalytic reaction of the graphene in the area of a cutting path under the participation of the active material. The active material is disposed on a surface of the cutting edge. The cutting edge is made of the active material in a section-wise manner. The cutting element is formed with a tip of a probe microscope. The catalytically active material comprises silver particle or tungsten particle. The heating device is configured to adjust a reaction temperature of 650-800[deg] C for the catalytic reaction by using the heat energy, and comprises a laser as heating agent. An independent claim is included for a method for cutting graphene using a cutting device.
