    摘要: This invention relates to flexible, transparent and conductive coatings and films formed using carbon nanotubes (CNT) and, in particular, single wall carbon nanotubes, with polymer binders. Preferably, coatings and films are formed from carbon nanotubes applied to transparent substrates forming one or multiple conductive layers at nanometer level of thickness. Polymer binders are applied to the CNT network coating having an open structure to provide protection through infiltration. This provides for enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or a combination thereof. Polymers may also be insulative or inherently electrical conductive, or any combination of both. Polymers may comprise single or multiple layers as a basecoat underneath a CNT coating, or a topcoat above a CNT coating, or combination of the basecoat and the topcoat forming a sandwich structure. A fluoropolymer containing binder, which is a solution of one fluoropolymer or a blend of fluoropolymers, which may be formulated with additives, is applied onto a carbon nanotube-based transparent conductive coating at nanometer level of thickness on a clear substrate such as PET and glass. The fluoropolymers or blend can be either semi-crystalline (with low level of crystallinity) or amorphous, preferably to be amorphous with low refraction index. Binder coating thickness can be adjusted by changing binder concentration, coating speed and/or other process conditions. This binder coating significantly improves optical transparency, and also maintain or increases conductivity of the CNT-based coating. With other benefits such as abrasion, thermal and moisture resistance, this binder coating and the resulting products is used for display and electronic applications.

    摘要: The present invention is directed to electrically conductive coatings of carbon that have high thermal oxidative stability and low thermal conduction. Coatings of the invention provide a surface resistivity to the coated substrate of 10 -2 ohms/square, and preferably 10 -2 ohms/square. Coatings also provide the coated article increased thermal oxidative stability as compared to the uncoated article and articles coated with convention materials like carbon black and metals, as well as low thermal conduction. The invention is also directed to substrates possessing conductive coatings, methods of utilizing the coated substrates, and to methods of forming the coatings of the invention.

    摘要: A conductive article includes a substrate and a conductive layer that is formed on the surface of the substrate and contains fine conductive fibers that are dispersed in the conductive layer. One end of the fibers is fixed to the substrate and other end of the fibers protrude from the top surface of the conductive layer. Alternatively, a middle portion of the fibers may protrude from the top surface or fixed to the substrate. Even though the fibers are dispersed well enough to avoid the aggregation of the fibers, portions of the fibers are located close to each other enough to provide electrical contact.
