Abstract

This invention relates generally to forming arrays of single-wall carbon nanotubes (SWNT). In one embodiment, the present invention involves forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of up to 106 single-wall carbon nanotubes into a composite array.

Independent Claims | See all claims (10)

  1. 1. A method of forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of at least about 106 single-wall carbon nanotubes into a composite array.
  2. 5. A method of forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of at least about 106 single-wall carbon nanotubes into a composite array wherein the subarrays are made according to the method comprising: (a) providing at least about 106 single-wall carbon nanotubes of substantially similar length in the range between 50 to 500 nm; (b) introducing a linking moiety onto at least one end of the single-wall carbon nanotubes; (c) providing a substrate coated with a material to which the linking moiety will attach; and (d) contacting the single-wall carbon nanotubes containing a linking moiety with the substrate, wherein the substrate comprises a substance selected from the group consisting of gold, mercury and indium-tin-oxide.
  3. 6. A method of forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of at least about 106 single-wall carbon nanotubes into a composite array wherein the subarrays are made according to the method comprising: (a) providing at least about 106 single-wall carbon nanotubes of substantially similar length in the range between 50 to 500 nm; (b) introducing a linking moiety onto at least one end of the single-wall carbon nanotubes; (c) providing a substrate coated with a material to which the linking moiety will attach; and (d) contacting the single-wall carbon nanotubes containing a linking moiety with the substrate, wherein the linking moiety comprises a moiety selected from the group consisting of —S—, —S—(CH2)n—NH—, and —SiO3(CH2)3NH—.
  4. 7. A method of forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of least about 106 single-wall carbon nanotubes into a composite array wherein the subarrays are made according to the method comprising: (a) providing a nanoscale array of microwells on a substrate; (b) depositing a metal catalyst in each of said microwells; and (c) directing a stream of hydrocarbon or CO feedstock gas at said substrate under conditions that effect growth of single-wall carbon nanotubes from each microwell.
  5. 9. A method of forming a macroscopic molecular array of tubular carbon molecules, said method comprising the step of assembling subarrays of at least about 106 single-wall carbon nanotubes into a composite array wherein the subarrays are made according to the method comprising: (a) providing a surface comprising purified single-wall carbon nanotube material; (b) subjecting the surface to oxidizing conditions sufficient to cause short lengths of broken single-wall carbon nanotubes to protrude up from the surface; and (c) applying an electric field to the surface to cause the single-wall carbon nanotubes to align in an orientation generally perpendicular to the surface and coalesce into an array.
