Patent number: 7378040Abstract: 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.Type: GrantFiled: August 11, 2005Date of Patent: May 27, 2008Assignee: Eikos, Inc.Inventors: Jiazhong Luo, David J.

Publication number: 20050266162Abstract: 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.Type: ApplicationFiled: March 14, 2005Publication date: December 1, 2005Inventors: Jiazhong Luo, Philip Wallis, David Arthur, Paul Glatkowski
