Abstract: Studying the fundamental interactions between polyelectrolytes and oppositely charged surfactants is important to a number of technologies, including adhesion, detergency and drug delivery. In this work, selfassembled charge alternating polyelectrolyte multilayers constructed by sequential adsorption of polycations and polyanions are studied. The inclusion of sodium dodecyl sulfate into the polyelectrolyte films is driven primarily by strong polycation-SDS electrostatic interactions and entropic gain via ion disassociation. This results in substantial changes in the wetting properties of these multilayer systems. In addition to ellipsometric measurements of film thickness and spectroscopic studies, dynamic surface tensiometry was used to determine advancing and receding contact angles of the film surfaces. Advancing contact angle measurements were used to determine the kinetics of SDS adsorption on polycation surfaces. Contact angle measurements were also utilized for obtaining information about surface wettabilty via concentration dependence of SDS and polycation PEI on respective surfaces.
