Abstract: The present disclosure provides an article having (a) a substrate having a first nanostructured surface that is antireflective when exposed to air and an opposing second surface; and (b) a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces defining a plurality of open area cells. The micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. The traces of the conductor micropattern have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. Each of the traces has a width from 0.5 to 10 micrometer. 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

Abstract: It has now been determined that a first coating layer may be applied to a substrate by a first coating die in a much thinner layer than its rheological properties and/or surface properties would normally allow. This is accomplished by using a second coating fluid dispensed from a second coating die acting as a "dynamic liquid squeegee" to transport, spread, even, or meter the first coating layer on the substrate by varying a gap between the second coating die and the substrate.
