▎ 摘　　要

NOVELTY - A nickel-based composite conductive ink comprises 46-65 pts. wt. conductive composite filler comprising nickel-nitrogen-doped graphene and molecular sieve, 10-15 pts. wt. binder, 0.5-2 pts. wt. defoaming agent, and 1.5-3 pts. wt. dispersion stabilizer. USE - Nickel-based composite conductive ink used in touch screen (claimed). ADVANTAGE - The nickel-based composite conductive ink with low electrical resistivity and improved electrical conductivity, and combines the silicon element in the molecular sieve to strengthen the adhesion between the conductive line and the substrate to avoid falling off. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nickel-based composite conductive ink, which involves mixing raw materials, stirring uniformly, ultrasonically processing for 12-15 minutes, reacting at 80-90 degrees C for 6-8 hours, cooling and drying.
