Self-assembly of lecithin in organic solvents can form reverse spherical micelles. Upon the addition of inorganic salts, reverse spherical micelles can be converted into reverse cylindrical micelles forming organogels. In this study, we investigated the effect of aromatic solvents such as benzene, toluene, and xylene on the formation of organogels from a mixture of lecithin and calcium chloride (CaCl2). Steady-shear and dynamic rheology were used to confirm the rheological properties of the samples. Fourier transfer infrared spectroscopy (FT-IR) was used to confirm the interactions of lecithin headgroups and CaCl2. The strength of the interaction is increased in the following order: benzene ＞ toluene ＞ xylene. We found that the strength of interactions is closely related to the rheological properties of the samples. |
