  • Publication number: 20080063585
    Abstract: This invention relates generally to a fullerene nanotube composition. The fullerene nanotubes may be in the form of a felt, such as a bucky paper. Optionally, the fullerene nanotubes may be derivatized with one or more functional groups. Devices employing the fullerene nanotubes of this invention are also disclosed.

  • Publication number: 20070048209
    Abstract: This invention relates generally to carbon fiber produced from fullerene nanotube arrays. In one embodiment, the present invention involves a macroscopic carbon fiber comprising at least 106 fullerene nanotubes in generally parallel orientation.

  • Publication number: 20070043158
    Abstract: This invention relates generally to a method for producing self-assembled objects comprising fullerene nanotubes and compositions thereof. In one embodiment, the present invention involves a three-dimensional structure of derivatized fullerene nanotubes that spontaneously form. It includes several components having multiple derivatives brought together to assemble into the three-dimensional structure. In another embodiment, objects may be obtained by bonding functionally-specific agents (FSAs) to groups of nanotubes, enabling them to form into structures. The bond selectivity of FSAs allow selected nanotubes of a particular size or kind to assemble together and inhibit the assembling of unselected nanotubes that may also be present.

  • Publication number: 20070003470
    Abstract: The present invention concerns a method for growing carbon nanotubes using a catalyst system that preferentially promotes the growth of single- and double-wall carbon nanotubes, rather than larger multi-walled carbon nanotubes. Ropes of the carbon nanotubes are formed that comprise single-wall and/or double-wall carbon nanotubes.

  • Publication number: 20050260120
    Abstract: This invention relates generally to a forming an array of single-wall carbon nanotubes (SWNT) in an electric field and compositions thereof. In one embodiment, a purified bucky paper of single-wall carbon nanotubes is used as the starting material. Upon oxidative treatment of the bucky paper surface, many tube and/or rope ends protrude up from the surface of the paper. Disposing the resulting bucky paper in an electric field results in the protruding tubes and or ropes of single-wall carbon nanotubes aligning in a direction substantially perpendicular to the paper surface. These tubes tend to coalesce to form a molecular array. In another embodiment, a molecular array of SWNTs can be made by “combing” the purified bucky paper starting material with a sharp microscopic tip to align the nanotubes.

  • Publication number: 20050249656
    Abstract: This invention relates generally to forming a patterned array of single-wall carbon nanotubes (SWNT). In one embodiment, a nanoscale array of microwells is provided on a substrate; a metal catalyst is deposited in each microwells; and a stream of hydrocarbon or CO feedstock gas is directed at the substrate under conditions that effect growth of single-wall carbon nanotubes from each microwell.

  • Publication number: 20050244326
    Abstract: The invention relates generally to dispersing and fractionating single-wall carbon nanotubes, which can be derivatized to facilitate fractionation, for example, by adding solubilizing moieties to the nanotubes.

  • Publication number: 20050244327
    Abstract: Single-walled carbon nanotubes have been synthesized by the catalytic decomposition of both carbon monoxide and ethylene over a supported metal catalyst known to produce larger multi-walled nanotubes. Under certain conditions, there is no termination of nanotube growth, and production appears to be limited only by the diffusion of reactant gas through the product nanotube mat that covers the catalyst The present invention concerns a catalyst-substrate system which promotes the growth of nanotubes that are predominantly single-walled tubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts.
