CONDUCTIVE ADHESIVE COMPOSITION

摘要

PURPOSE: An acryl conductive adhesive composition is provided to effectively improve conductivity and adhesion by having graphene with a conductive filler. CONSTITUTION: A conductive adhesive composition contains 100.0 weight parts of acrylic adhesive, 0.1-15 weight parts of graphene powder, and 0.1-10 weight parts of cross-linking agent. The composition further contains 0.001-30 weight parts of fatty acid having 5 or more carbon atoms. The cross-linking agent is a compound having two or more epoxy groups, isocyanate groups, amine groups, or aziridine groups. A method for adding fatty acid to the composition comprises a step of dispersing graphene in 20-200 times of solvent, a step of adding fatty acid having 5 or more fatty acid, a step of stirring strongly, and a step of treating the surface of the graphene.
