A method is disclosed which uses the Langmuir-Blodgett method to coat a substrate with multiple monomolecular single layers by immersing the substrate through a first layer of a first enclosure of a tank having first and second enclosures on a common subphase, and then withdrawing the substrate through a second layer in the second enclosure. The steps are repeatable to provide as many different single layers as required.
