Polyelectrolyte multilayers deposited by sequential spraying of poly(styrenesulfonate) and poly(diallyldimethylammonium) solutions are described. A highly uniform thin film is rapidly obtained over a large area. The morphology, uniformity, and chemical composition of sprayed multilayers, as well as the selective membrane properties, are found to be virtually identical to those prepared by dip-immersion.
