High density films of semiconducting single-walled carbon nanotubes having a high degree of nanotube alignment are provided. Also provided are methods of making the films and field effect transistors (FETs) that incorporate the films as conducting channel materials. The single-walled carbon nanotubes are deposited from a thin layer of organic solvent containing solubilized single-walled carbon nanotubes that is spread over the surface of an aqueous medium, inducing evaporative self-assembly upon contacting a solid substrate.

A method for producing a semiconducting SWCNT dispersion of the present invention comprises: a step A of preparing a to-be-separated SWCNT dispersion that includes a SWCNT mixture, an aqueous medium, and a polymer including a structural unit A derived from a monomer represented by Formula (1), and a step B of centrifuging the to-be-separated SWCNT dispersion and subsequently collecting a supernatant including the semiconducting SWCNT from the centrifuged to-be-separated SWCNT dispersion.

The present invention relates to elastomer compositions comprising adducts between compounds of formula (I) preferably derived from natural sources such as mucic, pyromucic, glucaric, glycaric, galactaric, muconic acid and/or linear derivatives thereof containing ester or amide groups and/or cyclic derivatives thereof with heteroatoms in the ring, such as oxygen or nitrogen, and carbon allotropes in which the carbon is sp.sup.2 hybridized, such as for example carbon nanotubes, graphene or nanographites, carbon black.

The present invention provides soluble single wall nanotube (SWNT) constructs functionalized with a plurality of a targeting moiety and a plurality of one or more payload molecules attached thereto. The targeting moiety and the payload molecules may be attached to the soluble SWNT via a DNA or other oligomer platform attached to the SWNT. These soluble SWNT constructs may comprise a radionuclide or contrast agent and as such are effective as diagnostic and therapeutic agents. Methods provided herein are to diagnosing or locating a cancer, treating a cancer, eliciting an immune response against a cancer or delivering an anticancer drug in situ via an enzymatic nanofactory using the soluble SWNT constructs.

The invention is directed to a method for attaching nanomaterials containing hexagonal lattices to polymer surfaces. For example, carbon nanotubes (CNTs) can be attached to polycarbonate, polyethylene, or epoxy surfaces by amination of the polymer surface, functionalization of the surfaces of CNTs with ester groups, and reacting the aminated surface of the polymer with the ester groups of the functionalized surfaces of the CNTs in an organic solvent to chemically bind the CNTs to the polymer surface.

The present invention relates to the production of a carbon material (eg a carbon nanomaterial) comprising single-walled carbon nanotubes (SWCNTs) and to the carbon material per se.

Disclosed herein is an apparatus and method for fabrication of large diameter single-walled carbon nanotube films. Advantageously, large diameter single-walled carbon nanotube films may be useful as transparent electrodes with high transparency and lower sheet resistance. In one embodiment, the method includes supplying carrier carbon monoxide and catalyst precursor through a first inlet at a temperature below the reaction temperature of the catalyst precursor; supplying heated carbon monoxide through a second inlet such that the heated carbon monoxide mixes with the carrier carbon monoxide and the catalyst an aerosol; reacting the aerosol in a reaction chamber to form a composite aerosol of single walled carbon nanotubes, metal nanoparticles, carbon monoxide, and carbon dioxide. In this embodiment, the heated carbon monoxide heats the catalyst precursor which reacts with the carbon monoxide to form carbon nanotubes.

The present invention relates to carbon nanostructure compositions such as single walled carbon nanotubes (SWCNT), and methods for purification thereof, such as separation by their electronic types (e.g., primarily semiconductor enrichment). The type separated, semiconducting SWCNTs, can be used in many downstream applications such as printed electronics, sensors, optoelectronics and solar energy conversion, among other applications.
