▎ 摘　　要

NOVELTY - A composite conductive ink comprises 10-20 pts. wt. resin, 10-20 pts. wt. graphene nano-silver powder, 10-20 pts. wt. organic solvent, 1-3 pts. wt. dispersant, 1-3 pts. wt. defoaming agent, and 1-3 pts. wt. antioxidant. USE - Composite conductive ink. ADVANTAGE - The composite conductive ink has excellent printability, low resistivity after printing, excellent and stable conductivity, and does not peel off easily. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite ink, which involves adding resin and organic solvent to high-speed shear disperser, dispersing for 20-40 minutes to obtain solution (A), slowly adding graphene nano-silver powder to solution (A), dispersing at high speed for 30-60 minutes, adding dispersant, defoaming agent and antioxidant, stirring for 20-40 minutes, ultrasonically dispersing mixture obtained for 2-4 hours, using three-roll mill to perform multiple grinding to obtain uniform slurry.
