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: 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: Metal salt based stabilizers are described that are effective to improve stability of sparse metal conductive films formed with metal nanowires, especially silver nanowires. Specifically, vanadium (+5) compositions can be effectively placed in coatings to provide desirable stabilization under accelerated wear testing conditions. Sparse metal conductive films can comprise fused metal nanostructured networks. Cobalt (+2) compounds can be incorporated as stabilization agents within nanowire inks to provide a high degree of stabilization without significantly interfering with the fusing process.

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.
