ABSTRACT:
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.
