PROCESS FOR PRODUCING PATTERNED COATINGS

摘要

Methods of producing patterned articles using a composition that includes a non-volatile component in a volatile liquid carrier, where the liquid carrier is in the form of an emulsion comprising a continuous phase and a second phase in the form of domains dispersed in the continuous phase.

1. A method of producing an article comprising:
(a) providing a composition comprising a non-volatile component in a volatile liquid carrier, wherein the liquid carrier is in the form of an emulsion comprising a continuous phase and a second phase in the form of domains dispersed in the continuous phase, (b) coating the composition on a surface of an unpatterned substrate and drying the composition to remove the liquid carrier while applying an outside force during the coating and/or drying to cause selective growth of the dispersed domains, relative to the continuous phase, in selected regions of the substrate, whereupon the non-volatile component self-assembles to form a coating in the form of a pattern that includes traces defining cells having a regular spacing, determined by the configuration of the outside force, on the surface of the substrate.
