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. (C) 2014 Elsevier B.V.
