1. A dispersion comprising:
a solvent;
graphenic carbon nanoparticles having an average aspect ratio of greater than 3:1 and a Raman 2D:G peak ratio of at least 1:1; and
a polymeric dispersant resin comprising an addition polymer comprising the residue of a vinyl heterocyclic amide in an amount of 0.5% to 99% by weight based on total weight of the addition polymer.
