Claim 0:
1. A method of forming a stable dispersion from a liquid phase nanoparticle blend, said nanoparticle blend comprising a first nanoscale material and a second nanoscale material, wherein said second nanoscale material acts as a dispersant, a surfactant, or a stabilizing molecule for the first nanoscale material, said method consisting of the steps of:
a) blending said first nanoscale material, said second nanoscale material acting as said dispersant, said surfactant, or said stabilizing molecule for the first nanoscale material, an optional dopant material, and at least one member selected from the group consisting of a polymer and at least one monomer for forming said polymer, with a solvent, so as to form a liquid phase nanoparticle blend, said second nanoscale material being present in said blend in an amount of from 5 wt. % to 500 wt. % of a total amount of the first nanoscale material present in the blend; and wherein said first nanoscale material is present in said blend in an amount of from about 1% to 5% of the blend;
b) processing said blend so as to deagglomerate and disperse the first nanoscale material as well as the second nanoscale material in said blend and thus to form said stable dispersion, in which 100% of the first nanoscale material dispersed in said stable dispersion remains in suspension for at least 24 hours and at least 70% of the first nanoscale material dispersed in said stable dispersion remains in suspension for at least one week;
wherein said solvent is selected so that the second nanoscale material acting as said dispersant, said surfactant, or said stabilizing molecule is soluble in said solvent;
wherein said first nanoscale material is not functionalized and consists of single-walled carbon nanotubes; wherein said second nanoscale material consists of graphene oxide.
