The structure of complexes between a cross-linked polyacrylic acid and a cationic surfactant such as cetyltrimethylammonium bromide (CTAB) has been studied by SANS and SAXS. The polycomplexes were found to be composed of a set of charged lamellae of surfactant ions embedded in the oppositely charged network of cross-linked polyacrylic acid via electrostatic interactions.
