US 12,630,691 B2 · Methods for forming dispersed carbon nanomaterials for use in polymer composites and coatings

Abstract

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.
