Researches on the structural self-organization and aggregation in aqueous liquid systems
of surfactants and polymers have been reviewed. Main attention is focused on the results
obtained for the interaction of ionic surfactants with non-ionic polymers. Capabilities
of the small-angle neutron scattering and neutron refiectometry methods for the study
of the micellar structure, micelle-polymer aggregates, and complex multicomponent
systems with nano particles are considered. Brief information is provided on some
complementary methods used for the structural analysis of liquid systems with self-organization.
