Comparative investigations of phase states, mesomorphic and morphologic properties in hexadecyltrimethyl ammonium bromide/water and hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic liquid crystalline systems

Abstract

In this work the phase equilibriums, the mesomorphic and morphologic properties of the binary hexadecyltrimethyl ammonium bromide/water and ternary hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic systems have been studied. The shape of micelles in the lyotropic phase has been estimated. Typical textures of the nematic–calamitic, nematic–discotic, hexagonal and lamellar mesophases and the phase diagrams of these lyotropic systems are presented.
