Multilayer films of cationic bilayer membranes were prepared by means
of alternate electrostatic adsorption with sodium poly-(styrenesulfona
te). Linear film growth was observed for at least 30 layers, as monito
red by UV spectroscopy and quartz crystal microbalance (QCM). A regula
r multilayer film of cationic bilayer membrane with anionic bilayer me
mbrane was similarly prepared.
