Lyotropic mesophase in amphiphile plus aliphatic alcohol mixtures with additions of water: mesomorphic, thermomorphologic, and optical refracting properties

Abstract

Amphiphile + aliphatic alcohol lyotropic systems with addition of water can form micelles with normal, mixed, and inverse type. Such systems display various types of mesophases and exhibit interesting structural, physical, and physicochemical properties. Therefore, lyotropic systems are important objects from both fundamental and application points of view. In this work, shape of anisometric micelles has been determined, and also, the magneto-morphologic properties of textures and optical refractive properties of mesophase have been investigated in hexadecyltrimethylammonium bromide (HDTMABr) + 1-decanol (DeOH) lyotropic system with various additions of water (H2O). Dependences of the magneto-morphologic properties vs. time have been obtained. Temperature and concentration dependences of the optical refractive index have been investigated. The effect of the DeOH/H2O concentration ratio on the refractive properties has been studied.
