Self-organization in complexes of polyacids with oppositely charged surfactants
Formation and structure of water-soluble complexes of alkyltrimethylammonium bromide homologues (AlkTAB) with poly(acrylic acid) (PA) of different polymerization degrees at pH 5.7 have been examined by elastic and quasi-elastic laser light-scattering and high-speed sedimentation technique. It was experimentally shown that generation of intramolecular micellar phase is the necessary condition for formation of PA-AlkTAB complexes. Minimum aggregation number of the surfactant ions in the complex micelle was found to be close to that of the surfactant micelles in polymer-free solution. The structure of the polyelectrolyte-surfactant complexes (i.e. a phase state of the complex, conformation of the polyion coil and the surfactant ion aggregation number) was shown to be largely determined by PA polymerization degree.
