▎ 摘　　要

NOVELTY - Graphene-based aqueous conductive ink comprises 1-8 pts. wt. expanded graphite, 10-30 pts. wt. conductive filler, 10-50 pts. wt. water soluble resin, 20-80 pts. wt. solvent and 1-10 pts. wt. auxiliary agent. USE - Used as graphene-based aqueous conductive ink. ADVANTAGE - The method is simple, and ensures short time consumption, and suitable for large scale production. The ink has good dispersibility and high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-based aqueous conductive ink, comprising (i) taking the raw materials of each component and weighing the solvent in the dark; and (ii) adding solvent, expanded graphite, water-soluble resin, conductive filler and auxiliary agent into a high-pressure homogenizer, shearing and grinding in the dark.
