<p>A coating mechanism disposes a liquid (e.g., polymer) thin film onto a conveyor surface (e.g., roller or belt) that is moved by a suitable motor to convey the thin film into a precisely controlled gap (or nip) region where applied potentials generate an electric field that causes the liquid to undergo Electrohydrodynamic (EHD) patterning deformation, whereby the liquid forms patterned micro-scale features. A curing mechanism (e.g., a UV laser) is used to solidify (e.g., cross-link) the patterned liquid features inside or immediately after exiting the gap region, thereby forming micro-scale patterned structures that are either connected by an intervening web as part of a sheet, or separated into discrete micro-scale structures. Nanostructures (e.g., nanotubes or nanowires) disposed in the liquid become vertically oriented during the EHD patterning process. Segmented electrodes and patterned charges are utilized to provide digital patterning control.</p> |
