It is known that lecithin, two tailed-surfactant, forms reverse spherical micelles by the self-assembly of molecules in a variety of nonpolar solvents. When certain additives are added to the lecithin solutions, diverse self-assembled structures such as reverse cylindrical micelles and reverse bilayer structures. In this study, we showed a simple method to create the reverse self-assembled structures by mixtures of lecithin and simple inorganic salts in cyclohexane. LiCl, CaCl2, and LaCl3 were used as inorganic salts. By controlling the concentration of the salts, diverse self-assembled structures such as reverse cylindrical micelles and reverse vesicles were created. Dynamic light scattering (DLS), small-angle-X-ray scattering (SAXS) and transmission electron microscope (TEM) were used to analyze the structures. |
