    摘要: The invention is directed to compositions and methods for forming conductive patterned coatings of carbon nanotubes. Patterns are electrically conductive coatings/films made by exploiting self patterning nanostructures composed of electrically conductive materials. The resulting layer is suitable for conducting electricity in applications where a transparent electrode is required. Typical applications include, but are not limited to; LC displays, touch screens, EMI shielding windows, and architectural windows. Films may be highly transparent. In one embodiment, carbon nanotubes are applied to an insulating substrate to form an electrically conductive network of nanotubes with controlled porosity in the network. The open area between the networks of nanotubes, increases the optical transparency in the visible spectrum while the continuous nanotube phase provides electrical conductivity across the entire surface or patterned area. Through the controlled application of this self assembled network of nanotubes by means of printing or spraying, patterned areas can be formed to function as electrodes in devices. The use of printing technology to form these electrodes obviates the need for more expensive process such as vacuum deposition and photolithography typically employed today during the formation of ITO coatings.

    摘要: This invention relates to flexible, transparent and conductive coatings and films formed using carbon nanotubes (CNT) and, in particular, single wall CNT, with polymer binders. Preferably, coatings and films are formed from CNT 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, and may comprise a basecoat, a topcoat, or a combination thereof, providing enhanced optical transparency, conductivity, moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics, thermosets, insulative, conductive or a combination thereof. A fluoropolymer containing binder is applied onto a CNT-based transparent conductive coating at nanometer level of thickness on a clear substrate. The fluoropolymers or blend can be either semi-crystalline or amorphous. This binder coating and the resulting products can be used for display and electronic applications.

    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.
