Lyotropic Lamellar Mesophase. Magneto-Morphologic Transformations and Optical Refracting Properties: Effect of Optically Active Dopants
Özet
Effect of optically active dopants on the morphologic and optical refracting properties of the lyotropic liquid crystalline mesophase with anisometric micelles has been investigated. Lyotropic lamellar mesophases, which are formed by the plate-like micelles of quasi-indefinite diameter, were objects of the investigations. Wine acid (WA) and tartaric acid (TA) were used as the optically active dopants. Texture transformations under influence of an external magnetic field and time and temperature changes of these textures for quaternary mixtures with various concentrations of the optically active dopants have been studied. Unusual textures with the spherical microdroplet formations have been found and studied. The optical refracting properties of ternary and quaternary lyotropic systems vs. temperature and concentration were investigated.
