▎ 摘  要

NOVELTY - Producing graphene powder comprises adding graphite blocks to a container, pouring a liquid, dipping the graphite blocks in the liquid using a brush and collecting the liquid, carrying out high-speed centrifugation at 1000-4000 revolutions per minute for more than 5 minutes to precipitate the unpeeled graphite particles and graphite sheet at the bottom of a centrifuge tube and concentrating the supernatant comprising graphene and multi-graphene particles, and separating the supernatant to obtain graphene powder or graphene solution. USE - The method is useful for producing graphene. ADVANTAGE - The method is carried out in a quick and easy manner, provides improved conductivity to graphene, and is convenient to use.
