▎ 摘  要

NOVELTY - Aqueous graphene conductive ink comprises 0.5-50 wt.% nano-volume tooth-shaped graphene micro-sheet dispersion liquid, 0-30 wt.% carbon nanotube dispersion, 1-10 wt.% conductive carbon black, 1-10 wt.% polymeric dispersing resin, 10-35 wt.% connecting resin, 0.5-6.5 wt.% additive and water (balance amount). USE - Used as aqueous graphene conductive ink. ADVANTAGE - The aqueous graphene conductive ink: prevents the stacking of graphene sheets, realizes the stable dispersion of graphene, and reduces the use of organic dispersants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous graphene conductive ink, comprising mixing nano-volume tooth-shaped graphene micro-sheet dispersion liquid, carbon nanotube dispersion, conductive carbon black with polymeric dispersing resin and antifoaming agent, then carrying out sand grinding treatment to particle size of less than 6 mu m to obtain composite conductive coarse slurry, then mechanically stirring and uniformly mixing the composite conductive coarse slurry and connecting resin, and adding auxiliary agent and modulating the ink to obtain aqueous graphene conductive ink.
