Abstract

This invention relates generally to a method for producing composites of single-wall carbon nanotubes (SWNTs) and compositions thereof. In one embodiment, the present invention involves a method of producing a composite material that includes a matrix and a carbon nanotube material embedded within said matrix. In another embodiment, a method of producing a composite material containing carbon nanotube material is disclosed. This method includes the steps of preparing an assembly of a fibrous material; adding the carbon nanotube material to the fibrous material; and adding a matrix material precursor to the carbon nanotube material and the fibrous material.

Independent Claims | See all claims (39)

  1. 1. A composite material comprising: (a) a matrix, wherein said matrix comprises a polymer; and (b) a single-wall carbon nanotube material embedded within said matrix, wherein said single-wall carbon nanotube material comprises fibers of greater than 106 single-wall carbon nanotubes.
  2. 9. A composite material comprising: (a) a matrix, wherein said matrix comprises a polymer; and (b) a single-wall carbon nanotube material embedded within said matrix, wherein said single-wall carbon nanotube material is derivatized to chemically react with said matrix material.
  3. 11. A method for producing a composite material comprising a single-wall carbon nanotube material, wherein said single-wall carbon nanotube material comprises fibers of greater than 106 single-wall carbon nanotubes, and wherein said method comprises: (a) preparing a matrix material; (b) combining said single-wall carbon nanotube material with said matrix material; and (c) forming said composite material.
  4. 13. A method of producing a composite material comprising carbon nanotube material, wherein said single-wall carbon nanotube material comprises fibers of greater than 106 single-wall carbon nanotubes, and wherein said method comprises: (a) preparing an assembly of a fibrous material; (b) adding said carbon nanotube material to said fibrous material; and (c) adding a matrix material to said carbon nanotube material and said fibrous material.
  5. 16. A composite material comprising carbon nanotubes, a fibrous structural constituent and a matrix material, wherein the matrix material comprises a polymer and the fibrous structural constituent comprises carbon, and wherein the carbon nanotubes comprise single-wall carbon nanotube fibers, wherein each of the single-wall carbon nanotube fibers comprises at least 106 individual single-wall carbon nanotubes.
  6. 29. A composite material comprising carbon nanotubes, a fibrous structural constituent and a matrix material, wherein the matrix material comprises a polymer, wherein the fibrous structural constituent comprises carbon, and wherein the carbon nanotubes comprise single-wall carbon nanotubes that have a homogeneous characteristic selected from the group consisting of lengths, diameters, helicities and combinations thereof.
  7. 30. A composite material comprising carbon nanotubes, a fibrous structural constituent and a matrix material, wherein (a) the matrix material comprises a polymer, (b) the fibrous structural constituent comprises carbon, (c) the carbon nanotubes comprise chemically-derivatized single-wall carbon nanotubes, chemically-derivatized ropes of single-wall carbon nanotubes, chemically-derivatized fibers or combinations thereof, (d) the chemically-derivatized single-wall carbon nanotubes have side-wall bonding sites, and (e) at least one of the side-wall defects comprises replacement of at least one carbon atom in the single-wall carbon nanotube lattice with at least one non-carbon atom.
  8. 32. A composite comprising derivatized single-wall carbon nanotubes and a polymer, wherein the polymer has at least one pendant group capable of a chemical reaction with the derivatized single-wall carbon nanotubes.
  9. 34. A method for producing a composite material comprising: (a) introducing a matrix material, wherein the matrix material comprises a polymer; (b) combining a carbon nanotube material with the matrix material, wherein the carbon nanotube material comprises a plurality of single-wall carbon nanotubes and wherein the single-wall carbon nanotubes are derivatized to facilitate bonding to other single-wall carbon nanotubes, the matrix material or both; and (c) subsequently forming the composite material.
