▎ 摘  要

NOVELTY - Preparing graphene or graphene oxide, comprises performing wet synthesis method to prepare carbon material, magnetic steel grinding body and solvent and then placing into a grinding container, arranging the container in a transformation space provided with a magnetic field for peeling off the mixture to obtain a graphene mixture, separating the mixture and then centrifuging to obtain a graphene transparent suspension, and performing dry method to prepare the carbon material and grinding body and then placing into container and arranging the container in the transformation space. USE - The method is useful for preparing graphene or graphene oxide. ADVANTAGE - The method is capable of rapidly preparing graphene or graphene oxide with high collision frequency. DETAILED DESCRIPTION - Preparing graphene or graphene oxide, comprises performing wet synthesis method to prepare carbon material, magnetic steel grinding body and solvent, placing the carbon material, magnetic steel grinding body and the solvent into a grinding container, sealing the container, arranging the container in a transformation space provided with a magnetic field for peeling off the mixture to obtain a nano-microchip graphene mixture, separating the graphene mixture and then centrifuging the graphene mixture to obtain a graphene transparent suspension, and performing dry method to prepare the carbon material and magnetic steel grinding body, placing the carbon material and magnetic steel grinding body into the grinding container, sealing the container and arranging the container in the transformation space provided with the magnetic field for peeling off the alkene to obtain nano-micro-graphite mixture of dry powder.
