The phase transition between nematic phases caused by formation of micelles in lyotropic liquid crystals

Abstract

The formation of micelles generally changes according to the concentration of surfactant molecules and temperature, and in particular rod or disk like micelles can cause lyotropic nematic phases. In this paper, we found that there are two different nematic phases caused by rod and disk like micelles in lyotropic liquid crystals by measurement of flow birefringence and investigated the phase transition between those two nematic phases by using differential scanning calorimetry.
