▎ 摘  要

NOVELTY - Preparing graphene comprises e.g. (i) carrying out graphite primary screening process to obtain the graphite raw material, (ii) under protective gas atmosphere, laser cracking graphite raw material, (iii) adding stripping agent after the cracking process of the graphite raw material, fully stirring for 1 hours to 30 minutes, stripping agent for the solvent molecule inserted layer to the interlayer of graphite to obtain graphite-release agent mixed solution, the stripping agent is surfactant, where the combining force greater than the graphite interlayer van der. USE - The method is useful for preparing graphene (claimed). ADVANTAGE - The method is simple, has high preparing efficiency, prepares graphene with high purity, and is environmentally friendly. DETAILED DESCRIPTION - Preparing graphene comprises (i) carrying out graphite primary screening process to obtain the graphite raw material, (ii) under protective gas atmosphere, laser cracking graphite raw material, (iii) adding stripping agent after the cracking process of the graphite raw material, fully stirring for 1 hours to 30 minutes, stripping agent for the solvent molecule inserted layer to the interlayer of graphite to obtain graphite-release agent mixed solution, the stripping agent is surfactant, where the combining force greater than the graphite interlayer van der, (iv) using the bubble generating device to graphite-stripping agent mixed solution in charging, gas filling thin graphite release agent hydrophobic end, resulting in bubbles, increasing acute large number volume, (v) using air explosion device detonated bubble by bubble explosion impact force again weakening the graphite interlayer bonding and weakening the bonding force between thin graphite with the stripping agent, graphite, graphene and obtaining stripping agent mixture, (vi) graphite, graphene obtained in the last step and stripping agent mixture to centrifugal dehydration treatment, drying treatment and sintering treatment, removing the stripping agent to obtain the mixture of graphite and graphene, (vii) using the mixture of graphite and graphene through extraction to extract, obtaining the graphene oxide mixed solution and graphite mixed solution, and (viii) graphene oxide mixed solution obtained by separating and drying after processing to obtain the graphene.
