Abstract
The present disclosure provides an article having a substrate having a first nanostructured surface and an opposing second surface; and a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces. The micropattern may have an open area fraction greater than 80%. The traces of the conductor micropattern may have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. The nanostructured surface may include nanofeatures having a height from 50 to 750 nanometers, a width from 15 to 200 nanometers, and a lateral spacing from 5 to 500 nanometers. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields.
