  • Patent number: 8865019
    Abstract: The method of inhibiting free radical polymerization of styrene includes adding multi-walled carbon nanotubes are added to the styrene monomer. The addition of the multi-walled carbon nanotubes at a concentration of 5% by weight is found to provide effective inhibition of the polymerization of the styrene. Greater decreases in the conversion rate of styrene to polystyrene are found through the addition of multi-walled carbon nanotubes functionalized with a carboxylic group (COOH). Still greater decreases in the conversion rate of styrene to polystyrene are found through the addition of multi-walled carbon nanotubes functionalized with octadecylamine (C18H39N). The multi-walled carbon nanotubes may also be functionalized with other functional groups, such as octadecanoate, polyethylene glycol or phenol. The functionalized multi-walled carbon nanotubes only require addition at a concentration of 1% by weight to be effective in polymerization inhibition.

  • Patent number: 8674134
    Abstract: Disclosed herein is a sequential functionalization methodology for the covalent modification of nanotubes with between one and four repeat units of a polymer. Covalent attachment of oligomer units to the surface of nanotubes results in oligomer units forming an organic sheath around the nanotubes, polymer-functionalized-nanotubes (P-NTs). P-NTs possess chemical functionality identical to that of the functionalizing polymer, and thus provide nanoscale scaffolds which may be readily dispersed within a monomer solution and participate in the polymerization reaction to form a polymer-nanotube/polymer composite. Formation of polymer in the presence of P-NTs leads to a uniform dispersion of nanotubes within the polymer matrix, in contrast to aggregated masses of nanotubes in the case of pristine-NTs.

  • Patent number: 8632633
    Abstract: Engineered defects are reproduced in-situ with graphene via a combination of surface manipulation and epitaxial reproduction. A substrate surface that is lattice-matched to graphene is manipulated to create one or more non-planar features in the hexagonal crystal lattice. These non-planar features strain and asymmetrically distort the hexagonal crystal lattice of epitaxially deposited graphene to reproduce “in-situ” engineered defects with the graphene. These defects may be defects in the classic sense such as Stone-Wales defect pairs or blisters, ridges, ribbons and metacrystals. Nano or micron-scale structures such as planar waveguides, resonant cavities or electronic devices may be constructed from linear or closed arrays of these defects. Substrate manipulation and epitaxial reproduction allows for precise control of the number, density, arrangement and type of defects. The graphene may be removed and template reused to replicate the graphene and engineered defects.

  • Publication number: 20130072669
    Abstract: The present invention is directed to carbon nanostructures, e.g., carbon nanotubes, methods of covalently functionalizing carbon nanostructures, and methods of separating and isolating covalently functionalized carbon. In some embodiments, carbon nanotubes are reacted with alkylating agents to provide water soluble covalently functionalized carbon nanotubes. In other embodiments, carbon nanotubes are reacted with a thermally-responsive agent and exposed to light in order to separate carbon nanotubes of a specific chirality from a mixture of carbon nanotubes.

  • Patent number: 8398234
    Abstract: Devices including a coating layer formed of a transparent, conductive coating composition described. The coating layer may function as an active antifog coating for the prevention of water vapor condensation as droplets on a surface. The coating includes a conductive polymer and functionalized carbon nanostructures and may be crosslinked with a transition metal crosslinking agent. The composition may be coated on a surface used in a visualization application such as a face shield, glasses, safety glasses, goggles, oculars, etc., to prevent fogging on the surface.

  • Patent number: 8365923
    Abstract: A method of separating at least one carbon nanotube having a desired diameter and/or chirality from a mixture of carbon nanotubes having different diameters and/or chiralities is provided. A calixarene of formula (I): wherein n?4; X is PO3H2, Ra—PO3H, SO3H, or Ra—SO3H; Y is Rb, OH, or ORb; and Ra and Rb are independently selected from the group consisting of optionally substituted alkyl, optionally substituted aryl, optionally substituted arylene alkyl and optionally substituted alkylene aryl is combined with the mixture of carbon nanotubes in an aqueous solvent to produce an aqueous supernatant containing the carbon nanotube(s) having the desired diameter and/or chirality. The aqueous supernatant containing the carbon nanotube(s) is then separated from a residue comprising the remaining carbon nanotubes of the mixture.

  • Patent number: 8318250
    Abstract: Anchored nanostructure materials and methods for their fabrication are described. The anchored nanostructure materials may utilize nano-catalysts that include powder-based or solid-based support materials. The support material may comprise metal, such as NiAl, ceramic, a cermet, or silicon or other metalloid. Typically, nanoparticles are disposed adjacent a surface of the support material. Nanostructures may be formed as anchored to nanoparticles that are adjacent the surface of the support material by heating the nano-catalysts and then exposing the nano-catalysts to an organic vapor. The nanostructures are typically single wall or multi-wall carbon nanotubes.
