The present disclosure describes methods of deagglomerating, debundling, dispersing, and functionalizing carbon nanomaterials in a medium using a process that does not damage the properties of the carbon nanomaterials. Three exemplary types of carbon nanomaterials are conductive carbon black, graphene, and carbon nanotubes (CNT), including single-wall carbon nanotubes (SWCNT). Once the carbon nanomaterials are dispersed in the medium, the resulting carbon nanomaterial dispersion can be subjected to further processing or blended with additional components to form a coating or polymer composite material suitable for molding structural components. The dispersed carbon nanomaterial can provide the resulting part or component with desirable mechanical and electrical properties such as static dissipation and conductivity.

A method for making electrically conductive patterns using a metal particle-free ink containing a catalyst precursor that subsequently forms catalytic seed nanoparticles in-situ during or after a patterning step. The catalytic pattern is fixed on the target substrate after which catalytic sites are generated by reduction of the precursor to metallic particles.
