Claim 12:
13. A method of forming a polymeric nanocomposite material including a first nanoscale material and a second nanoscale material, wherein said second nanoscale material is present in an amount from 5 wt. % to 500 wt. % of the total amount of the first nanoscale material, said method comprising:
a) blending said first and second nanoscale materials, and a monomer or monomers of a polymer with a solvent, in order to form a blend thereof; and wherein said first nanoscale material is present in said blend in an amount of from about 1% to 5% of the blend; and
b) processing said blend so as to deagglomerate and disperse the first nanoscale material as well as the second nanoscale material in said blend, said second nanoscale material acting as a dispersant or a surfactant for said first nanoscale material, and thus to form a stable dispersion in which 100% of the first nanoparticle 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;
and c) forming the polymeric nanocomposite material by polymerization of said monomer or monomers in the stable dispersion; and
wherein said first nanoscale material is not functionalized and consists of single-walled carbon nanotubes;
wherein said second nanoscale material is graphene oxide;
wherein said blend includes no other dispersant and no other surfactant besides said second nanoscale material; and wherein said solvent is selected so that said second nanoscale material acting as said dispersant or said surfactant is soluble in said solvent;
whereby washing and/or rinsing the polymeric nanocomposite material produced in step c) in order to improve at least one property of said polymeric nanocomposite material is eliminated by including the graphene oxide in said blend, said at least one property being selected from the group consisting of electrical conductivity, thermal conductivity, optical properties, magnetic properties, kinetic properties and mechanical properties of the polymeric nanocomposite material.
