  • Publication number: 20220177720
    Abstract: A method of forming a conductive film. The method includes applying an ink onto a substrate. The ink includes a plurality of nanostructures formed from an electrically-conductive material and a polymer binder. The method includes drying the ink on the substrate. The method includes applying an overcoat material solution onto the dried ink. The overcoat solution includes at least some solvent suitable to provide at least some solubility of the binder. Also, a conductive film that includes a substrate, a matrix on the substrate, and a plurality of nanostructures within the matrix. The matrix is provided as a resultant of a polymer binder present within an ink that carried the nanostructures that was applied and dried upon the substrate, a dried/cured overcoat material that that was applied on the dried ink layer in the form of a coating solution that included a polymer and at least some solvent to provide at least some solubility of the binder, with the binder being at least partially dissolved.

  • Publication number: 20220172859
    Abstract: A transparent, electrically-conductive film and associated method of making the transparent, electrically-conductive film. The transparent, electrically-conductive film includes a substrate, a percolating network of nanostructures establishing electrical conductivity across a region of the substrate, and an overcoat matrix coated onto the substrate. The nanostructures have an average diameter value. The percolating network of nanostructures is located within the overcoat matrix. The overcoat matrix and the percolating network of nanostructures therein have an overall thickness that is less than four times the average diameter value of the nanostructures.

  • Publication number: 20220020508
    Abstract: An electrically-conductive film that includes a substrate and a plurality of metal nanostructures supported on the substrate, with the nanostructures connecting to provide a network having electrical conductivity along the network. The film includes a first overcoat matrix on the nanostructures and the substrate, and can includes a second overcoat matrix on the nanostructures and the first overcoat matrix. The second overcoat matrix can have a thickness sufficient to cover the nanostructures and the first overcoat matrix. The film allows an electrical contact material that extends through the second overcoat matrix to electrically connect to the nanostructures at a contact area. The first overcoat matrix can have a thickness within a range of 1 to 3 average diameter of the nanostructures. The combination of the first overcoat matrix and second overcoat matrix can fully cover the nanostructures.

  • Patent number: 10580549
    Abstract: A method of fabricating a transparent conductor includes the following steps. The first step is drawing a substrate from a first reel to a second reel along a travelling path, and along the travelling path. Next step is forming a metal nanowire dispersion layer on the substrate and then drying the metal nanowire dispersion layer to form a metal nanowire network layer. Next step is forming a matrix layer on the metal nanowire network layer so as to form a conductive layer of the metal nanowire network layer embedded in the matrix layer.
