▎ 摘  要

NOVELTY - Provided is a preparation method of sheet-like graphene, which includes the steps of: (a) providing a graphene precursor; and (b) carrying the graphene precursor in a supersonic speed airstream to be collided with a collision plate for forming a plurality of sheet-like graphene. The preparation method of sheet-like graphene in accordance with the present invention can produce a sheet-like graphene with a uniform thickness distribution, and is provided with the advantages of simplification, low cost, and satisfaction at industrial mass production. In addition, the graphene precursor in step (a) is selected from the group consisting of graphite, expansion graphite, insertion graphite, delamination graphite, oxidization graphite or a combination thereof, and the supersonic speed airstream in step (b) is generated by compressing air in a pressure range of 0.1-1.6 MPa and enabling the compressed air to pass through a spray nozzle.
