Conductive trace hiding materials, articles, and methods |
| 摘要 |
An article includes a patterned substrate including a substrate surface with an inorganic electro-conductive trace adjacent thereto (wherein the substrate and the inorganic material of the trace each has an index of refraction), and a layer including a polymerized acrylate matrix adjacent to at least a portion of the surface of the substrate and the inorganic electro-conductive trace, wherein the layer has an index of refraction that is within ±10% of the average of the indices of refraction of the substrate and the inorganic material of the trace. |

1. An article comprising:
a patterned substrate comprising a substrate surface with an inorganic electro-conductive trace adjacent thereto, wherein the substrate and the inorganic material of the trace each has an index of refraction; and a layer comprising a polymerized acrylate matrix adjacent to at least a portion of the surface of the substrate and the inorganic electro-conductive trace, wherein the polymerized acrylate matrix has an index of refraction that is within ±10% of the average of the indices of refraction of the substrate and the inorganic material of the trace; wherein the polymerized acrylate matrix comprises inorganic nanoparticles having an index of refraction of 1.6 or higher dispersed therein; and wherein the polymerized acrylate matrix comprises aromatic groups derived from acrylate monomers having an index of refraction of 1.55 or higher. |
