Abstract
A method for forming channels within a dried chromonic layer is described. A coating composition is applied to a substrate, dried, and exposed to a hydrophilic organic solvent forming a channel pattern having a first set of channels, and a second set of channels that are substantially perpendicular to the first set of channels. A deposition material may be disposed within the channels to form a nanostructured pattern. An article having a channel pattern is further described.
