A transparent conductor including a conductive layer coated on a substrate is described. More specifically, the conductive layer comprises a network of nanowires which may be embedded in a matrix. The conductive layer is optically transparent and flexible. It can be coated or laminated onto a variety of substrates, including flexible and rigid substrates.

Transparent conductors comprising metal nanowires

A patterned transparent conductor includes a substrate and additives at least partially embedded into at least one surface of the substrate and localized adjacent to the surface according to a pattern to form higher sheet conductance portions. The higher sheet conductance portions are laterally adjacent to lower sheet conductance portions.

Low-haze transparent conductors

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 from 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 Olims/square or a transparency to visible light of at least about 90% and a sheet resistance of no more than about 250 Olims/square. In addition to maintaining good transparency, the materials formed from the sintered metal nanowire networks can have a haze of no more than 0.5. 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.
