Graphenic carbon nanoparticles that are dispersed in solvents through the use of dispersant resins are disclosed. The graphenic carbon nanoparticles may be milled prior to dispersion. The dispersant resins may comprise a polymeric dispersant resin comprising an addition polymer comprising the residue of a vinyl heterocyclic amide, an addition polymer comprising a homopolymer, a block (co)polymer, a random (co)polymer, an alternating (co)polymer, a graft (co)polymer, a brush (co)polymer, a star (co)polymer, a telechelic (co)polymer, or a combination thereof. The solvents may be aqueous, non-aqueous, inorganic and/or organic solvents. The dispersions are highly stable and may contain relatively high loadings of the graphenic carbon nanoparticles.
