Abstract

The vesicle structure and interfacial structure of a two-chain amphiphile didodecyldimethylammonium bromide (DMA) in aqueous colloid have been studied by small-angle x-ray scattering. The radius of the DMA small vesicle is ca. 64 Å, and the thickness of the bilayer, which is the surface layer of the vesicle, is ca. 41 Å. The small vesicle has a core space at the center, whose radius is ca. 23 Å. The specific inner surface of the small vesicle has also been calculated and the surface area of the vesicle has been estimated to be five times larger than that of the smooth sphere.
