Abstract:
A method of applying a coat of a substance onto one side only of a substrate, comprising the steps of:mixing the substance in a solvent to provide 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 an accessible undisturbed free surface, positioning the one side only in contact with and at a predetermined angle to the accessible undisturbed free surface, so that a single meniscus is formed in the solvent mix extending between the undisturbed free surface and the one side only, and separating the one side only and the solvent mix at a separation rate so that the single meniscus traverses the one side only at a rate related to a solvent evaporation rate.
