▎ 摘  要

NOVELTY - A graphene organic slurry comprises graphene whose solid content is 0.1-5 wt.%. The oxygen content in graphene is 10-25 wt.%. USE - Graphene organic slurry (claimed). ADVANTAGE - The graphene organic slurry has excellent dispersibility in water, reduced synchronization in graphene oxide during solvent substitution process, reduced production cost, content of graphene is more than 0.05 wt.%, improved reduction effect under heating condition at 150 degrees C, and oxygen content is reduced to 20 wt.%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of graphene organic slurry, which involves using graphene oxide aqueous solution as raw material, mixing with organic solvent in which the dispersant is dissolved, homogenizing, removing water from the solvent to obtain graphene organic slurry, where content of the oxidized graphene in aqueous solution of graphene oxide is 1-2%, the aqueous solution of graphene oxide is prepared by adding oxidized graphite to water, mechanical stripping to form aqueous graphene oxide solution, mechanical peeling, high-speed shearing or ultrasonically treating, and treating with high shear emulsifier at 1500 rpm for 60 minutes.
