Abstract: Transparent conductive films comprising sparse metal conductive layers are processed after coating with an overcoat to lower the sheet resistance of the film. The sparse metal conductive layer can comprise a fused metal nanostructured network. A coating, such as a polymer overcoat or a polymer undercoat can noble metal ions that can further reduce the sheet resistance with the application of heat and optionally humidity. In particular, silver ions in a coating are demonstrated to provide important stabilization of sparse metal conductive layers, whether or not fused, upon the application of heat and humidity. A coating can further comprise a metal salt stabilization composition.

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: Highly uniform and thin silver nanowires are described having average diameters below 20 nm and a small standard deviation of the diameters. The silver nanowires have a high aspect ratio. The silver nanowires can be characterized by a small number of nanowires having a diameter greater than 18 nm as well as with a blue shifted narrow absorption spectrum in a dilute solution. Methods are described to allow for the synthesis of the narrow uniform silver nanowires. Transparent conductive films formed from the thin, uniform silver nanowires can have very low levels of haze and low values of ΔL*, the diffusive luminosity, such that the transparent conductive films can provide little alteration of the appearance of a black background.

Abstract: Metal nanowires with uniform noble metal coatings are described. Two methods, galvanic exchange and direct deposition, are disclosed for the successful formation of the uniform noble metal coatings. Both the galvanic exchange reaction and the direct deposition method benefit from the inclusion of appropriately strong binding ligands to control or mediate the coating process to provide for the formation of a uniform coating. The noble metal coated nanowires are effective for the production of stable transparent conductive films, which may comprise a fused metal nanostructured network.

Abstract: Optically transparent films can comprise a coating of nanodiamonds to introduce desirable properties, such as hardness, good thermal conductivity and an increased dielectric constant. In general, transparent conductive films can be formed with desirable property enhancing nanoparticles included in a transparent conductive layer and/or in a coating layer. Property enhancing nanoparticles can be formed from materials having a large hardness parameter, a large thermal conductivity and/or a large dielectric constant. Suitable polymers are incorporated as a binder in the layers with the property enhancing nanoparticles. The coatings with property enhancing nanoparticles can be solution coated and corresponding solutions are described.

Abstract: Polymer binders, e.g., crosslinked polymer binders, have been found to be an effective film component in creating high quality transparent electrically conductive coatings or films comprising metal nanostructured networks. The metal nanowire films can be effectively patterned and the patterning can be performed with a high degree of optical similarity between the distinct patterned regions. Metal nanostructured networks are formed through the fusing of the metal nanowires to form conductive networks. Methods for patterning include, for example, using crosslinking radiation to pattern crosslinking of the polymer binder. The application of a fusing solution to the patterned film can result in low resistance areas and electrically resistive areas. After fusing the network can provide desirable low sheet resistances while maintaining good optical transparency and low haze. A polymer overcoat can further stabilize conductive films and provide desirable optical effects. The patterned films can be useful in devices, such as touch sensors.
