wide area transparent conductive coatings including doped carbon nanotube and nanowire composites and methods for their production

摘要

wide area transparent conductive coatings including doped carbon nanotube and nanowire composites and methods for their production. Certain exemplary embodiments of this invention pertain to wide area transparent conductive (tccs) coatings including carbon nanoweb (cnts) and nanowire composites and methods for their production. The sym dc / sym opt ratio of these thin films can be enhanced by stable chemical doping and / or alloying of cnt-based films. doping and / or alloying may be implemented in a wide area coating system, for example on glass and / or other substrates. in certain exemplary embodiments, a cnt film may be deposited and then doped by chemical functionalization and / or bonded with silver and / or palladium. p-type and n-type dopants may be used in different embodiments of this invention. In certain exemplary embodiments, silver and / or other nanowires may be provided, for example, to further decrease sheet strength. Certain exemplary embodiments may provide coatings that approach, reach or exceed 90% transmission and 90 ohms / square of target metrics.
