Аннотация:Surface modifi cation of polystyrene and Nafion™ fi lms with a cationic polyelectrolyte poly(diallyldimethylammonium chloride), or PDADMAC, through adsorption of the polyelectrolyte from its aqueous solutions was studied. It was established that the PDADMAC adsorption layers strongly adhere to the polystyrene fi lms, thus hydrophilizing their surface. Attempts to modify the surface of Nafion™ films revealed that PDADMAC is localized in channels of the swollen polymer fi lm without any noticeable eff ect on the characteristics of the film surface.
