  • Publication number: 20170067166
    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.

  • Publication number: 20160108256
    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.

  • Publication number: 20150144380
    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.

  • Publication number: 20140238833
    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.

  • Publication number: 20130342221
    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.

  • Publication number: 20130341074
    Abstract: Metal nanowires, such as silver nanowires coated on a substrate were fused together to form fused metal nanowire networks that have greatly improved conductivity while maintaining good transparency. Materials formed form the fused metal nanowire networks described herein can have a transparency to visible light of at least about 85% and a sheet resistance of no more than about 100 Ohms/square or a transparency to visible light of at least about 90% and a sheet resistance of no more than about 250 Ohms/square. 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. When formed into a film, materials comprising the metal nanowire network demonstrate low sheet resistance while maintaining desirably high levels of optical transparency, making them suitable for transparent electrode formation.
