  • Patent number: 8535753
    Abstract: Methods of forming carbon nanotubes include forming a catalytic metal layer on a sidewall of an electrically conductive region, such as a metal or metal nitride pattern. A plurality of carbon nanotubes are grown from the catalytic metal layer. These carbon nanotubes can be grown from a sidewall of the catalytic metal layer. The plurality of carbon nanotubes are then exposed to an organic solvent. This step of exposing the carbon nanotubes to the organic solvent may be preceded by a step of applying centrifugal forces to the plurality of carbon nanotubes. Alternatively, the exposing step may include applying a centrifugal force to the plurality of carbon nanotubes while simultaneously exposing the plurality of carbon nanotubes to an organic solvent.

    Abstract: A gas sensor utilizing carbon nanotubes (CNTs) is disclosed. The sensor can include a patch antenna, a feed line, and a stub line. The stub line can include a carbon nanotube (CNT) thin-film layer for gas detection. The CNTs can be functionalized to detect one or more analytes with specificity designed to detect, for example, environmental air contaminants, hazardous gases, or explosives. The sensor can provide extremely sensitive gas detection by monitoring the shift in resonant frequency of the sensor circuit resulting from the adsorption of the analyte by the CNT thin-film layer. The sensor can be manufactured using inkjet printing technologies to reduce costs. The integration of an efficient antenna on the same substrate as the sensor enables wireless applications of the sensor without additional components, for wireless standoff chemical sensing applications including, for example, defense, industrial monitoring, environmental sensing, automobile exhaust analysis, and healthcare applications.

  • Patent number: 8460747
    Abstract: Certain example embodiments of this invention relate to large-area transparent conductive coatings (TCCs) including carbon nanotubes (CNTs) and nanowire composites, and methods of making the same. The ?dc/?opt ratio of such thin films may be improved via stable chemical doping and/or alloying of CNT-based films. The doping and/or alloying may be implemented in a large area coating system, e.g., on glass and/or other substrates. In certain example embodiments, a CNT film may be deposited and then doped via chemical functionalization and/or alloyed with silver and/or palladium. Both p-type and n-type dopants may be used in different embodiments of this invention. In certain example embodiments, silver and/or other nanowires may be provided, e.g., to further decrease sheet resistance. Certain example embodiments may provide coatings that approach, meet, or exceed 90% visible transmission and 90 ohms/square target metrics.

  • Patent number: 8455043
    Abstract: Disclosed herein is a method of fabricating a transparent conductive film, including preparing a carbon nanotube composite composition by blending a carbon nanotube in a solvent; coating the carbon nanotube composite composition on a base substrate to form a carbon nanotube composite film, and acid-treating the carbon nanotube composite film by dipping the carbon nanotube composite film in an acid solution, followed by washing the carbon nanotube composite film with distilled water and drying the washed carbon nanotube composite film to form a transparent electrode on the base substrate. The transparent conductive film can have excellent conductivity, transparency and bending properties following acid treatment, so that it can be used in touch screens and transparent electrodes of foldable flat panel displays. Further, the carbon nanotube composite conductive film can have improved conductivity while maintaining transparency after acid treatment.
