Abstract

A method of making a composite material includes disposing a carbon-based particulate material, such as graphene or carbon nanotubes, in an activation solution and activating surfaces of the carbon-based particulate material using the activation solution. Once the surfaces of the carbon-based particulate material have been activated, a metallic coating is applied to the activated surfaces to form a composite material. The composite material is then recovered as a particulate material formed having carbon-based particulate material with a metallic coating that is suitable for fusing together for forming electrical conductors, such as with an additive manufacturing technique.
