Lecithin, an amphiphilic surfactant, self-assembles into spherical reverse micelles in various organic solvents. When salts with low solubility in organic solvents interact with the hydrophilic head group of lecithin, their solubility increases significantly, triggering structural changes in the lecithin molecules. These changes induce the transformation of spherical reverse micelles into cylindrical reverse micelles, and as these cylindrical micelles form a network, significant changes in the rheological properties occur. In this study, two different salts are simultaneously added to lecithin solutions to investigate the formation of self-assembled nanostructures and the resulting rheological changes. Small-angle X-ray scattering (SAXS) and rheological analyses are employed to quantitatively examine the changes in the nanostructures' morphology and physical properties.
