摘要：

A light scattering study of cetyltrimethylammoniumhydroxynaphthalene carboxylate (CTAHNC) is presented. In the concentration range studied (0.07-0.6 mM) the structure of the micellar aggregate is likely to be vesicles of size similar to 100 nm. HNC- is expected to act as a co-surfactant which reduces the bending rigidity, k(c), of the bilayer membrane leading to a rough and undulating surface for the vesicles. The fractal dimension d approximate to 2-2.6, which fits the light scattering data, supports this view. A scanning electron micrograph at a higher concentration indicates that the aggregates are vesicles.
