  • Patent number: 8080199
    Abstract: The present invention is directed toward methods of crosslinking carbon nanotubes to each other using microwave radiation, articles of manufacture produced by such methods, compositions produced by such methods, and applications for such compositions and articles of manufacture. The present invention is also directed toward methods of radiatively modifying composites and/or blends comprising carbon nanotubes with microwaves, and to the compositions produced by such methods. In some embodiments, the modification comprises a crosslinking process, wherein the carbon nanotubes serve as a conduit for thermally and photolytically crosslinking the host matrix with microwave radiation.

  • Publication number: 20080210370
    Abstract: The present invention is directed to the creation of macroscopic materials and objects comprising aligned nanotube segments. The invention entails aligning single-wall carbon nanotube (SWNT) segments that are suspended in a fluid medium and then removing the aligned segments from suspension in a way that macroscopic, ordered assemblies of SWNT are formed. The invention is further directed to controlling the natural proclivity or nanotube segments to self assemble into or ordered structures by modifying the environment of the nanotubes and the history of that environment prior to and during the process. The materials and objects are “macroscopic” in that they are large enough to be seen without the aid of a microscope or of the dimensions of such objects.

  • Patent number: 7252812
    Abstract: This invention is directed to the fluorination (or derivatization with alternative chemical species) of fullerene carbon nanocages as an efficient way to (a) facilitate synthesis of endohedral complexes by a significant reduction or elimination of the barriers for the entry of guest-ions, -atoms or molecules, and (b) to preserve the chemical stability of final product.

  • Publication number: 20020027312
    Abstract: A method of modifying a physical property of a nanotube comprises subjecting a nanotube having a defined lattice structure orientation to stress conditions sufficient to disrupt the lattice structure and form a dipole of dislocation cores therein, and wherein the dipole of dislocation cores split and propagate in the nanotube in a manner such that the dipole of dislocation cores are separated by at least one domain of modified structure, and wherein the physical property of the nanotube are altered.
