Textures nematic MCLCP

The effect of structural disclinations upon texture and the origins of these in local deformations of or discontinuities in the arrangement of the molecules have been studied only in the case of nematic MCLCPs. The primacy aim of this chapter is therefore to present to the reader defects and textures in nematic MCLCPs. Some of consequences of constructing a nematic phase from long... 

The evolution from the static state to different textures observed as a consequence of controlled shearing experiments and the subsequent relaxation behavior at the cessation of flow were first analyzed by Grazia-no and Mackley [96] for a number of thermotropic MCLCPs. This pioneering work introduced and defined the terms used today to classify shear-induced textures worm texture, ordered texture and banded texture. It should be noted that these textures have also been observed in lyotropic nematics.
