Abstract: A formable transparent conductive film are described that comprise a sparse metal conductive layer, a thermoplastic polymer substrate supporting the sparse metal conductive layer, a viscoelastic polymer with a thickness from about 15 microns to about 150 microns over the sparse metal conductive layer. A layered film structure can be formed that is suitable for contouring on the surface of a three dimensional object without unacceptable increases in sheet resistance and with good optical transparency and low haze. The formable films can be placed into a frozen configuration bent 90 degrees with a radius of curvature of no more than about 5 centimeters while exhibiting a surface resistance of no more than about 500 ohms/sq. with a total transmittance with respect to visible light of at least about 80%.

Abstract: Inks for the formation of transparent conductive films are described that comprise an aqueous or alcohol based solvent, carbon nanotubes as well as suitable dopants. Suitable dopants generally comprise halogenated ionic dopants. In some embodiment, the inks comprise sulfonated dispersants that can effectively provide additional doping to improve electrical conductivity as well as stabilize the inks with respect to settling and/or improve the fluid properties of the inks for certain processing approaches. The inks can be processed into films with desirable levels of electrical conductivity and optical transparency.

Abstract: Transparent conductive films are described based on sparse metal conductive layers. Stabilization with respect to degradation of electrical conductivity over time is provided for the sparse metal conductive layers through the design of additional layers in the film. Specifically, the sparse metal conductive layer can be placed adjacent coatings with appropriate stabilization compositions as well as through the incorporation into the film of various additional protective layers.
