摘要：

It is known, that block copolymers consisting of a polyelectrolyte block and a neutral hydrophilic block co-assemble with oppositely charged ionic surfactants to form various nanosized structures. We report on studies of complex nanoaggregates of cationic perfluorinated surfactant N-(1,1,2,2-tetrahydroperfluorodecyl)pyridinium chloride and of double hydrophilic block polyanion poly(ethylene oxide)-b-poly((2-sulfamate-3-carboxylate)isoprene) the latter being biocompatible, with polyelectrolyte block containing both strong (SO3H) and weak (COOH) acidic groups. The study was aimed at the characterization of the association behavior of the block copolymer-fluorosurfactant systems in aqueous solutions depending on the amount of the added surfactant, pH of the solvent and the structure of the copolymers.
