Title: Structural evolution of reverse vesicles from a salt-free catanionic surfactant system in toluene
Abstract: A detailed study of the reverse vesicles formed by a salt-free surfactant system in toluene was carried out by confocal microscopy observations, dye-solubilizing tests, UV-vis and cryo-TEM observations. When tetradecyltrimethyl laurate (TTAL) and lauric acid (LA) were mixed in the binary of water and toluene, reverse vesicular phase formed The reverse vesicular phase is quite stable and can be with fluorescent dyes for subsequent confocal fluorescence observations. However, the reverse vesicles were found to smaller sizes (<1 mu m) and undergo structural evolutions in a much time scale compared to those formed by the same surfactant in cyclohexane, as shown in a previous report [}19]. With observation time, interesting intermediate structures were including onions, sheets and cellular networks. The structural pathways were deduced and the possibly influencing factors discussed. Dye-solubilizing tests showed the ability of the reverse to accommodate dye molecules is smaller compared to those in Besides, cryo-TEM observations were applied to probe the of the reverse vesicles.
