▎ 摘　　要

NOVELTY - Preparing graphene using jet involves keeping graphite block (10) in nozzle (21) of a jet machine (20) and then starting jet machine to obtain small size primary graphite (32) and fluid (30). The fluid is injected into one end of the graphite block. The graphite block is sprayed with primary graphite. The upper surface and residual fluid on lower surface of graphite block are cleaned. The cleaned graphite block is embedded with primary graphite material at one end. The graphene layer is removed and steps are repeated to obtain sufficient number of graphene. USE - Method for preparing graphene using jet (claimed). ADVANTAGE - The method enables to prepare graphene using jet has ensured easy separation of large size and predetermined shape of the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene sheet embedded between layers. Graphite block (10) Jet machine (20) Nozzle (21) Fluid (30) Primary graphite (32)
