Patent ID: 7683098

Claim:
A concentrated dispersion comprising a nanomaterial and a solvent composition; wherein a Hansen interface match index between the nanomaterial and the solvent composition is less than 50, wherein the bulk density of the concentrated dispersion is at least three times higher than the bulk density of the nanomaterial in dry form, wherein the concentrate requires less volume to store and transport over that required for dry nanomaterial, wherein the nanomaterial loading in the concentrated dispersion is at least 55% by weight, and wherein the solvent composition has percentage contribution values for Hansen parameters that are selected from one of the following four combinations: 1) non-polar 33%-49%, polar 11%-29%, and hydrogen bonding 28%-47%; 2) non-polar 40%-63%, polar 14%-33%, and hydrogen bonding 14%-41%; 3) non-polar 31%-53%, polar 12%-33%, and hydrogen bonding 27%-43%; or 4) non-polar 68%-91%, polar 12%-31%, and hydrogen bonding 9%-28%.
