▎ 摘　　要

NOVELTY - The preparation method of graphene slurry involves preparing acrylonitrile oligomer by liquid-phase synthesis method to obtain graphene powder, ball-milling the graphene powder, and dissolving dispersant in solvent to obtain mixed solution, adding the graphene powder after milling treatment to the mixed solvent, and uniformly dispersing. USE - Preparation method of graphene slurry (claimed) used for electric conduction and heat conduction. ADVANTAGE - The method enables preparation of graphene slurry with excellent dispersibility, high stability, and high concentration, by simple and environmentally-friendly process.
