▎ 摘　　要

NOVELTY - Manufacture of graphene platelets involves providing several graphite blocks between every two graphene layers which are bonded by Vander Waals forces, placing the graphite block in a chamber, introducing forward airflow and reverse airflow into the chamber, applying a shear airflow produced by the airflow interface to the graphite block, and collecting several pieces of graphene platelets. Each of graphite blocks comprises several stacked graphene layers. The shear airflow has a kinetic energy for damaging the Vander Waals force to disengage a portion of the graphene layers. USE - Manufacture of graphene platelets (claimed). ADVANTAGE - The method enables simple and quick manufacture of graphene platelets with excellent productivity, transparency, electroconductivity, heat conductivity and ductility, and high strength-to-weight ratio. DETAILED DESCRIPTION - Manufacture of graphene platelets involves providing (1) several graphite blocks between every two graphene layers which are bonded by Vander Waals forces, placing (2) the graphite block in a chamber, introducing forward airflow and reverse airflow into the chamber, applying (3) shear airflow produced by the airflow interface to the graphite block, and collecting (4) several pieces of graphene platelets. Each of graphite blocks comprises several stacked graphene layers. The forward airflow forms flow path (p1) in the chamber, the reverse airflow forms flow path (p2) in the chamber, and airflow interface forms between the flow path (p1) and the flow path (p2). The shear airflow has a kinetic energy for damaging the Vander Waals force to disengage a portion of the graphene layers. The graphene platelets comprise one or multiple of graphene layers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the manufacture of graphene platelets. Provision of graphene blocks (1) Placement of graphene blocks in chamber (2) Application of shear airflow generated by airflow interface to graphite blocks (3) Collection of disengaged graphene platelets (4)
