Abstract

The disclosure relates to a metal nanowire structure. The metal nanowire structure includes a substrate and a metal nanowire film located on the substrate. The metal nanowire film includes a number of first metal nanowires parallel with and spaced from each other. A width of each of the plurality of first metal nanowires is in a range from about 0.5 nanometers to about 50 nanometers. Each of the plurality of first metal nanowires is a solid structure and consists of metal material.

First claim

What is claimed is:

1. A metal nanowire structure comprising:
a substrate having a surface; and
a metal nanowire film located on the surface of the substrate; wherein the metal nanowire film comprises a plurality of first metal nanowire bundles, the plurality of first metal nanowire bundles are parallel with and spaced from each other, each of the plurality of first metal nanowire bundles comprises a plurality of first metal nanowires parallel with each other and parallel with the surface of the substrate, and a first distance between adjacent first metal nanowires is less than a second distance between adjacent first metal nanowire bundles; wherein each of the plurality of first metal nanowire bundles further comprises a plurality of second metal nanowires randomly arranged and in contact with the plurality of first metal nanowires; the plurality of first metal nanowire bundles and the plurality of first metal nanowires have the same length, and the plurality of second metal nanowires is shorter than the plurality of first metal nanowires.

2. The metal nanowire structure of claim 1 , wherein the first distance ranges from about 0 nanometers to about 50 nanometers; and the second distance ranges from about 10 micrometers to about 100 micrometers.

3. The metal nanowire structure of claim 1 , wherein a first width of each of the plurality of first metal nanowire bundles ranges from about 50 micrometers to about 500 micrometers; and a second width of each of the plurality of first metal nanowires ranges from about 0.5 nanometers to about 50 nanometers.

4. The metal nanowire structure of claim 1 , wherein a material of the plurality of first metal nanowires is selected from the group consisting of gold, silver, copper, iron, aluminum, nickel and chromium.

5. The metal nanowire structure of claim 1 , wherein the substrate comprises rigid materials selected from the group consisting of silicon, ceramic, glass, quartz, diamond, metal oxide and plastic.

6. The metal nanowire structure of claim 1 , wherein the substrate comprises flexible materials selected from the group consisting of polycarbonate, polymethyl methacrylate acrylic, polyethylene terephthalate, polyether polysulfones, polyvinyl polychloride, benzocyclobutenes, polyesters, polyimide, polyethylene, acrylonitrile-butadiene-styrene copolymer, polyamide, polybutylene terephthalate, and acrylic resins.
