▎ 摘　　要

NOVELTY - An ink comprises 20-40 %mass conductive graphite, 0-20 %mass conductive carbon black, 0.1-5 %mass graphene, where graphene is self-made graphene oxide, 20-40 %mass water-based resin, 30-55 %mass solvent, 0.05-0.15 %mass dispersant and 0.08-1 %mass additive. USE - Ink. ADVANTAGE - The aqueous conductive ink can be prepared economically by using homemade graphene oxide. Mixing conductive graphite, conductive carbon black and graphene and cross-linking can form a stable structure, which effectively overcomes poor stability of existing conductive inks. The graphene has excellent conductivity which improves the conductive properties of conductive inks. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of ink which involves adding conductive graphite, solvent and dispersant to high-speed disperser, stirring, dispersing uniformly to obtain graphene coarse slurry, transferring the coarse slurry obtained to a nano-sand machine for grinding to obtain a finely-ground graphene fine slurry, adding the graphene fine slurry and aqueous resin to the high-speed mixer, adding additives, stirring at high speed, mixing well and sieving.
