Abstract
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.
Claims48
A transparent conductor comprising:
- a substrate;
- and
- a conductive layer on the substrate, the conductive layer including a plurality of metal nanowires,
- wherein the metal nanowires intersect and form a plurality of nanowire crossing points, and wherein at each of at least some of the crossing points, at least one of the intersecting nanowires has a flattened cross section, wherein the conductive layer includes a matrix that includes:
- an acrylate monomer;
- a multifunctional acrylate monomer;
- and at least one photoinitiator.
A transparent conductor comprising a substrate;
- and a conductive layer on the substrate, the conductive layer including a plurality of metal nanowires and a matrix polymerized from:
- an acrylate monomer:
- 2-ethylhexyl acrylate;
- a multifunctional acrylate monomer:
- trimethylolpropane triacrylate (TMPTA);
- an adhesion promoter;
- and
- at least one photoinitiator.
A patterned transparent conductor comprising:
- a substrate;
- a conductive region on the substrate, the conductive region including a plurality of interconnecting metal nanowires;
- and
- a non-conductive region on the substrate, wherein the conductive region and the non-conductive region are arranged in a predetermined pattern, wherein the non-conductive region includes metal nanowires at a lower concentration than that of the plurality of interconnecting metal nanowires in the conductive region.
A transparent conductor comprising:
- a substrate;
- a conductive layer on the substrate, the conductive layer including a plurality of metal nanowires, and
- a matrix on the conductive layer, wherein the matrix is a conductive polymer, wherein the conductive polymer is poly(3,4-ethylenedioxythiophene), polyaniline, polythiophene, or polydiacetylene.
A patterned transparent conductor comprising:
- a substrate;
- a conductive region on the substrate, the conductive region including a plurality of interconnecting metal nanowires;
- and
- a non-conductive region on the substrate, wherein the conductive region and the non-conductive region are arranged in a predetermined pattern, wherein the non-conductive region has no metal nanowires.
