Abstract

The adsorption features of aqueous PEI/SDS solutions on silica surfaces were investigated by ellipsometry. Results were compared with the interfacial behavior of the SDS solutions on preadsorbed PEI layers. It was shown that the properties of the mixed surface layers can be well interpreted via the individual adsorption properties of PEI as well as the characteristics of its interaction with SDS in the bulk solution.
