摘要：

Static and dynamic light scattering and conductivity experiments were carried out on salt-free aqueous micellar solutions of cetyltrimethylammonium n-hexane sulfonate (CTAC(7)SO(3)) and cetyltrimethylammonium n-heptane sulfonate (CTAC(7)SO(3)) as a function of surfactant concentration. This study confirms the analogy between the behavior in the semi-dilute regime of elongated micellar systems and "classical" polyelectrolyte solutions. Time-resolved scattering experiments performed after a variation of concentration from about twice the overlap volume fraction Phi* to less than half of it revealed the existence of a structural relaxation with a characteristic time of several hours.
