▎ 摘  要

NOVELTY - Graphene-based aqueous conductive ink comprises 5-10 pts. wt. water-soluble resin, 2-10 pts. wt. conductive filler, 0.5-2 pts. wt. dispersing agent, 5-15 pts. wt. graphene and 65-85 pts. wt. solvent. USE - Used as graphene-based aqueous conductive ink. ADVANTAGE - The conductive ink: has excellent dispersion property, strong stability, strong anti-stripping performance, excellent conductivity and flexibility, and folding resistance; has no emission of organic volatile substances; is environmentally friendly; and does not agglomerate easily. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene-based aqueous conductive ink, comprising (i) carrying out pre-dispersion of raw materials at speed of 300-350 revolutions/minute for 10-60 minutes to obtain mixed liquid, (ii) dispersing the mixed liquid in high-pressure homogenizer, where the pressure of the high-pressure homogenizer is 200-900 bar, and flow rate is 100-500 l/hour, and (iii) discharging the mixed liquid from homogenizer, and post-treating.
