▎ 摘  要

NOVELTY - Self-stabilized dispersed graphene nano material, prepared by liquid phase stripping method from sodium p-aminobenzenesulfonate, natural flake graphite and alcohol-water mixed solvent, where sodium p-aminobenzenesulfonate acts on the surface of graphene by pi - pi conjugation, physical adsorption and chemical grafting. USE - Used as self-stabilized dispersed graphene nano material. ADVANTAGE - The self-stabilized dispersed graphene nano material: has good water-dispersion ability, excellent electrical conductivity and easy industrial production and has great potential in graphene application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing self-stabilized dispersed graphene nano material, comprising (i) mixing natural flake graphite, alcohol-water mixed solvent and sodium p-aminobenzenesulfonate, and sonicating to obtain graphite dispersion in which sodium p-aminobenzenesulfonate is completely dissolved; (ii) feeding above graphite dispersion into a grinder for grinding to obtain polishing slurry; and (iii) subjecting above-mentioned polishing slurry to centrifugal washing with washing solvent to obtain precipitate, which is the self-stabilizing dispersed graphene nano material.
