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. 公开了通过使用分散剂树脂分散在溶剂中的石墨烯碳纳米粒子。可在分散之前研磨所述石墨烯碳纳米粒子。所述分散剂树脂可包含聚合物分散剂树脂，所述聚合物分散剂树脂包含有包含乙烯基杂环酰胺残基的加聚物、包含均聚物、嵌段(共)聚合物、无规(共)聚合物、交替(共)聚合物、接枝(共)聚合物、刷状(共)聚合物、星形(共)聚合物、遥爪(共)聚合物或其组合的加聚物。所述溶剂可以是水性、非水性、无机和/或有机溶剂。分散体高度稳定并且可含有相对高负载量的所述石墨烯碳纳米粒子。
