▎ 摘  要

NOVELTY - Graphene ink comprises conductive metal particles comprising a first metal particle comprising a dendritic structure and a second metal particle coated on a surface of the first metal particle, and graphene filler. USE - The ink is useful for electromagnetic wave shielding film (claimed). ADVANTAGE - The ink has improved electrical conductivity in vertical direction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing graphene ink, comprising (a) mixing conductive metal particles, graphene filler, binder resin, solvent, curing agent and other additives to prepare mixed solution, and (b) dispersing the mixed solution, where the conductive metal particles include a first metal particle comprising a dendritic structure and a second metal particle coated on a surface of the first metal particle.
