Abstract:
A method of applying a coating of a substance onto an article, wherein the article includes a coating-only surface on which the substance is to be coated and one or more other surfaces on which the substance is not to be coated comprising the steps of:providing a predetermined concentration of the substance in a solvent mix; placing an amount of the solvent mix in a container so that the solvent mix has a coating contact surface, wherein the coating contact surface comprises a substantially undisturbed free surface and is accessible for contact by the coating-only surface; positioning the coating-only surface in contact with and at a predetermined angle to the coating contact surface, so that a single meniscus is formed in the solvent mix extending between the coating contact surface and the coating-only surface; and separating the coating-only surface and the solvent mix at a separation rate so that the single meniscus traverses the coating-only surface at a rate related to a solvent evaporation rate.
