Abstract
The present disclosure provides an article having (a) a substrate having opposing first and second surfaces; and (b) a conductor micropattern disposed on the first surface of the substrate. The conductor micropattern has a plurality of traces defining a plurality of open area cells. The conductor micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. Each of the traces is non-linear and has a trace 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.
