The cellular optical texture of the lyotropic nematic phase of the caesium pentadecafluoro-octanoate(CsPFO)/water system in cylindrical tubes

Abstract

Abstract The nematic phase of the CsPFO/water system, when held in a cylindrical glass tube, spontaneously forms a detailed ‘cellular’ texture with an axial S = +1 disclination. This texture is the lyotropic discotic analogue of that previously found for a calamitic thermotropic system.
