Abstract: Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors.

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: Metal nanowires, such as silver nanowires coated on a substrate were sintered together to form fused metal nanowire networks that have greatly improved conductivity while maintaining good transparency and low haze. The method of forming such a fused metal nanowire networks are disclosed that involves exposure of metal nanowires to various fusing agents on a short timescale. The resulting sintered network can have a core-shell structure in which metal halide forms the shell. Additionally, effective methods are described for forming patterned structure with areas of sintered metal nanowire network with high conductivity and areas of un-sintered metal nanowires with low conductivity. The corresponding patterned films are also described. When formed into a film, materials comprising the metal nanowire network demonstrate low sheet resistance while maintaining desirably high levels of optical transparency with low haze, making them suitable for transparent electrode, touch sensors, and other electronic/optical device formation.

Abstract: Structures are described having thin flexible polymer substrates with electrically conductive films on each opposing surface while having high optical transmittance and good optical properties. The structures can have total thicknesses of no more than about 30 microns and good flexibility. Processing approaches are described that allow for the coating of the very thin structures by providing support through the coating process. The structures are demonstrated to have good durability under conditions designed to test accelerated wear for touch sensor use.

Abstract: Nanoscale colorants are introduced to adjust the hue of transparent conductive films, such as to provide a whiter film. The transparent conductive films can have sparse metal conductive layers, which can be formed using silver nanowires. Color of the film can be evaluated using standard color parameters. In particular, values of color parameter b* can be reduced with the nanoscale colorants without unacceptably changing other parameters, such as haze, a* and transparency.

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: 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: 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.
