The disclination in nematic phase of polymeric liquid crystals shows the schlieren texture with different number of dark brushes under polarized optical microscope

which is really a optical effect of the director orientation. In recent years

the study of disclination structure of liquid crystalline polymers is making great progress. The lamellar decoration

banded texture decoration and surface crack decoration have been developed to show the morphology of disclination in nematic phase of liquid crystalline polymers. In this paper the disclination structure in nematic phase and its new research development have been reviewed.
