▎ 摘　　要

NOVELTY - A graphene-modified nano metallic conductive ink comprises 10-30 pts. wt. electroconductive material, 1-10 pts. wt. graphene-metal nanoparticle composite, 1-5 pts. wt. cetyltrimethylammonium chloride, 1-5 pts. wt. organically modified polydimethylsiloxane, 45-80 pts. wt. binder, 5-20 pts. wt. solvent, and 1-5 pts. wt. auxiliary agent. USE - Graphene-modified nano metallic conductive ink (claimed). ADVANTAGE - The graphene-modified nano metallic conductive ink is economical, and has excellent electroconductivity, and low metal content as compared with the existing ink. The film of the graphene-modified nano metallic conductive ink has excellent adhesiveness and flexibility and high hardness.
