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