PROBLEM TO BE SOLVED: To provide a plate-shaped graphene production method that, since its process is complicated and a production speed is low, simplifies a production process and improves productivity.SOLUTION: A method for producing plate-shaped graphene 30 includes: providing a plurality of graphite block materials 10; using a cutting air flow 24 generated at an air flow joining point 23 of a forward air flow 20a and a reverse air flow 20b between a first flow passage 21 and a second flow passage 22 and having kinetic energy destroying a van der Waals force to act on the graphite block materials 10 to partially desorb a graphene layer 11; and collecting plural pieces of plate-shaped graphene 30 comprising one or more graphene layers 11 partially desorbed from the graphite block material 10. The production method desorbs the graphene layer 11 from the graphite block material 10 using the cutting air flow 24 to form a plate-shaped graphene 30, whereby the production process can be simplified and rapid mass production can be performed.SELECTED DRAWING: Figure 2 |
