Polymer binders for flexible and transparent conductive coatings containing carbon nanotubes

InactiveUS20050209392A1Decrease in optical transparencyDecrease in surface conductivityMaterial nanotechnologySpecial tyresThermoplasticCarbon nanotube
This invention relates to flexible, transparent and conductive coatings and films formed using single wall carbon nanotubes and polymer binders. Preferably, coatings and films are formed from carbon nanotubes (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. This provides for the enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or any combination of both. 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. Binder coating thickness can be adjusted by changing binder concentration, coating speed and / or other process conditions. Resulting films and articles can be used as transparent conductors for flat panel display, touch screen and other electronic devices.
