▎ 摘　　要

NOVELTY - Aqueous graphene slurry comprises an aqueous dispersion and a graphene material dispersed in the aqueous dispersion, where the aqueous dispersion includes surfactant and the graphene has a mass of 0.2-12 wt.% based on 100% of the total mass of graphene aqueous slurry. USE - The aqueous graphene slurry is useful in the fields of conductive heat conductive coatings, anticorrosive coatings, batteries or supercapacitors. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing an aqueous graphene slurry, comprising using graphite oxide solid or expandable graphite solid as a raw material, performing expansion treatment to prepare expanded graphite, and soaking the expanded graphite in an aqueous stripping solution, obtaining a mixture containing expanded graphite, subjecting the expanded graphite-containing mixture to high speed shearing or ultrasonic treatment, removing the aqueous stripping solution, obtaining a graphene wet material, placing the graphene wet material in an aqueous dispersion and performing high speed shearing.
