▎ 摘　　要

NOVELTY - Aqueous graphene conductive ink composition comprises 5-20 pts. wt. conductive unit, 20-25 pts. wt. connecting agent, 5-10 pts. wt. auxiliary agent and 45-70 pts. wt. water. The conductive unit comprises graphene and modified conductive carbon black. USE - The composition is useful for printed circuits, membrane switches, radio frequency identification, smart packaging and electromagnetic shielding. ADVANTAGE - The composition can obtain the aqueous graphene conductive ink with low conductive unit content, excellent mechanical properties and high conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing aqueous graphene conductive ink using the aqueous graphene conductive ink composition, comprising uniformly mixing the graphene, modified conductive carbon black and the auxiliary agent, and adding the connecting agent for stirring to obtain the aqueous graphene conductive ink; aqueous graphene conductive ink prepared by the preparation method; and use of aqueous graphene conductive graphite, comprising printed circuits, membrane switches, radio frequency identification, smart packaging and electromagnetic shielding.
