Structural fixation of spontaneous vesicles in aqueous mixtures of polymerizable anionic and cationic surfactants

摘要: Two polymerizable surfactants, cationic methacryloyloxyundecyl trimethylammonium bromide and anionic sodium 4-(ω-methacryloyloxyundecyl)oxy benzene sulfonate, have been synthesized. The microstructures formed by mixtures of these surfactants in aqueous solution include stable vesicles, the structure which can be fixed polymerization. Both native polymerized vesicles are characterized using quasi-elastic static light scattering, small-angle neutron cryogenic transmission electron microscopy. Polymerization captures bilayer without creating appreciable intervesicle cross-linking.
