Textures in Nematic Main-Chain Liquid Crystalline Polymers

Defects and Textures in Nematic Main-Chain Liquid Crystalline Polymers 

As pointed out by Kleman in early 1985 [24], liquid crystalline polymers (LCPs) and LMWLCs are equivalent from the point of view of topology since they exhibit the same symmetries and the same type of order parameters. Defects are indeed characteristic breaks in local symmetry of the order parameter and can be classified according to their dimensionality and the specific sym- 

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
