▎ 摘　　要

NOVELTY - Silver-graphene composite ink comprises a silver-graphene composite having a core containing silver and a graphene shell covering the core; and a binder in which the silver-graphene composite is dispersed. The binder is included in ratio of 20-30 pts. wt. based on 100 pts. wt. of the total weight of the ink. USE - The silver-graphene composite ink is useful for printing conductive patterns (claimed). ADVANTAGE - The silver-graphene composite ink has excellent electrical conductivity, acid resistance, chemical resistance, and moisture resistance, and can be provided in form of conductive ink having fluidity suitable for printing through composition design. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for printing conductive patterns, comprising (a) preparing silver-graphene composite ink, (b) applying the silver-graphene composite ink on a substrate, and (c) sintering the silver-graphene composite ink applied on the substrate, where the silver-graphene composite ink includes a silver-graphene composite having core containing silver and graphene shell covering the core, and a binder in which the silver-graphene composite is dispersed.
