Abstract

An electrically conductive adhesive composition, free of metals and metal salts, includes an adhesive polymer component selected from polyethylene-vinyl acetate, polyolefin elastomers, polyvinyl butyral, poly(acrylic acid), polyacrylates and poly(methyl methacrylate) from 5% to 40% by weight, an electrically conductive component including acetylene or carbon black nanoparticles, carbon nanotubes, and flakes or plates of graphene or graphene derivatives from 60% to 95% by weight, percentages by weight of the adhesive polymer component and electrically conductive component, the electrically conductive component consisting of acetylene or carbon black nanoparticles from 15% to 45% by weight, carbon nanotubes from 5% to 25% by weight, and flakes or plates of graphene or graphene derivatives from 35% to 70% by weight, percentages by weight of the electrically conductive component, and a solvent compatible with the adhesive polymer component from 50% to 90% by weight of the electrically conductive adhesive composition.
