英文摘要: Steady fluorescence and dynamic light-scattering measurement were reported for dodecyldimethylammoniopropanesulfonate (DDAPS)/NaCl aqueous micellar system. The results show that the aggregation number and the hydrodynamic radius of DDAPS micelles increase slightly with the increasing of NaCl concentration and decrease slightly as the temperature rises. For the zwitterionic surfactant system we infer repulsive intermicellar interactions in spite of the absence of net charges. DDAPS behaves somewhat like an ionic surfactant, Within the scope of our investigation, DDAPS micelles exist in spherical shape. Keywords Dodecylimethylammoniopropanesulfonate, Aggregation number , Hydrodynamic radius, Fluorescence, Light-scattering.
