Abstract
Methods for manufacturing nanomaterial dispersions, such as nanomaterial concentrates, and related nanotechnology are provided. The nanomaterial concentrates provided can be more cheaply stored and transported compared to non-concentrate nanomaterial forms.
Claims16
A composition of matter comprising
- a concentrated dispersion of a nanomaterial and a solvent composition,
- 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, and
- wherein the nanomaterial loading in the concentrated dispersion is at least 40% by weight.
