▎ 摘  要

NOVELTY - Copper-graphene composite ink comprises copper-graphene composite having a core containing copper and a graphene shell covering the core, epoxy compounds, amine-based curing agent, and acid anhydride curing agent. USE - The copper-graphene composite ink is useful in circuit of an electronic device. ADVANTAGE - The copper-graphene composite ink: has excellent conductivity; prevents oxidation by moisture or oxygen; is suitable for use in implementing a flexible electronic device; is economical; has excellent acid resistance, chemical resistance, and moisture resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for conductive pattern printing comprising (1) preparing a copper-graphene composite ink, (2) applying the copper-graphene composite ink on a substrate, and (3) sintering the copper-graphene composite ink applied on the substrate.
