| 20090131554 | ELECTROMAGNETIC SHIELDING COMPOSITE COMPRISING NANOTUBES - There is provided an electromagnetic (EM) shielding composite and its method of manufacture having low observability and a low loading level, e.g., 1.5 weight percent, of nanotubes mixed in a base host polymer, wherein the EM shielding composite is an effective shield and absorber for broadband plane wave EM radiation. The loading levels of nanotubes are sufficiently low to leave the mechanical properties of the base polymers essentially unchanged, making this approach widely applicable to a broad range of applications. | 05-21-2009 |

| 20090068241 | DEPOSITION OF METALS ONTO NANOTUBE TRANSPARENT CONDUCTORS - This invention is directed to compositions and methods of incorporating metal particles into carbon nanotube films, sheets, and networks. Metal salts that are soluble in water, alcohol, polar organic solvents, and mixtures thereof are used to deposit metal particles onto carbon nanotube films, sheets, and networks. Metal salts increase conductance of nanotube films by spontaneously depositing gold on the nanotube. The concentration and time of exposure to metal salt solution allows the tuning of conductivity and transparency for a transparent carbon nanotube network. Metal salts added to nanotube ink add functional properties of the metal to nanotube conductors. | 03-12-2009 |
| 20100028634 | METAL OXIDE COATINGS FOR ELECTRICALLY CONDUCTIVE CARBON NANOTUBE FILMS - This invention are directed to methods and compositions preferably comprising non-silicate metal oxides as a treatment for transparent electrically conductive carbon nanotube coatings that prevents resistance changes during exposure to environmental conditions; both chemical effects (for example, water, heat, light, or other compounds) and physical effects (for example, abrasion, scratch, adhesion). The protective properties instilled by these coatings occur preferably through the careful selection of the appropriate metal oxide depending on the application. | 02-04-2010 |
| 20100136224 | STABLE NANOTUBE COATINGS - The present invention relates to purified transparent carbon nanotube (CNT) conductive layers or coatings that comprise at least one additional material to form a composite. Adding a material to the CNT layer or coating improves conductivity, transparency, and/or the performance of a device comprising a transparent conductive CNT layers or coating This composite may be used in photovoltaic devices, OLEDs, LCD displays, or touch screens. | 06-03-2010 |

| 20080281030 | Polymer nanocomposites and methods of preparation - High-use temperature, lightweight polymer/inorganic nanocomposite materials are described having enhanced thermal stability and performance characteristics. These materials are made possible by new methods for synthesizing composite materials that enhance the thermal stability of the nanocomposite systems from 100-150° C. to over 450° C. These materials and techniques for their formation are enabled at least in part by the use of polar organic phthalonitrile monomers and oligomers that can exfoliate layered phyllosilicates, such as smectite clays, in percentages greater than 10% inorganic by weight. This approach offers a solvent-free direct melt intercalation technique that greatly reduces the cost of processing nanocomposites. Additionally, the use of unmodified phyllosilicates overcomes temperature limitations of prior art, which uses organically-modified layered silicates. The new technology provides hitherto unobtainable thermal stability and performance characteristics, and has numerous applications in the automotive, aerospace, electronic and marine industries. | 11-13-2008 |
