X–Ray study of structural changes in the liquid crystal systemAOT / N–Heptane–Water depending on the concentration of components

Abstract

The work investigated the structural changes of the multicomponent liquid crystal system sodium salt of di– (2–ethylhexyl) ester of sulfosuccinic acid (AOT) –n–heptane – water depending on the concentration of AOT in a mixed solution by X–ray diffraction. The studies were carried out in a wide concentration range from 27 to 92% AOT in a mixed solvent with an initial n–heptane / water ratio of 5.8. The studies were carried out with a gradual decrease in the n–heptane / water ratio to the content of bound water in the system and an increase in the concentration of AOT in the solution to 92%. The mesomorphism of the liquid crystal system is established depending on the content of the concentration of the components and the region of the compact liquid crystal lamellar “smooth” phase for modeling biological membranes is established
