▎ 摘  要

NOVELTY - Manufacturing two-dimensional material through dry exfoliation comprises introducing grinding air and feeding air into a dry jet mill, injecting the raw material (graphite powder or graphite flakes) into a dry jet mill into which the grinding air and the feeding air are introduced and exfoliating the raw materials, and obtaining a two-dimensional material i.e. graphene exfoliated from the dry jet mill, generating oil-free compressed air by the grinding air and the feeding air, removing moisture by passing the compressed air through a moisture removal filter, removing moisture by passing the compressed air through a refrigeration dryer and removing moisture by passing the compressed air through an adsorption dryer, where the pressure of the grinding air is 2-10 bar, and the pressure of the feeding air is 0.1-0.3 bar. USE - The method is useful for manufacturing two-dimensional material i.e. graphene for electronic application. ADVANTAGE - The method: shortens the exfoliation time and quantity; is highly efficient and environmentally-friendly; and does not use a solvent and does not generate the waste.
