Surface effects on lyotropic liquid crystals

Abstract

Liquid crystals are very sensitive to surface e ects. In fact, these e ects are very useful in designing eletro-optical devices. We present a review of the theoretical models that describe the surface interactions in liquid crystals, focusing on lyotropic systems. Experimental results will be presented and compared to theoretical predictions.

Texture transformations and orientational properties of lyotropic nematics in magnetic field

“…These mesophases are the optically uniaxial nematic-calamitic N C mesophase, the optically uniaxial nematic-discotic N D mesophase and the optically biaxial N bx mesophase. These mesophases are constructed by micelles with short-range positional and long-range orientational order [1][2][3][4][5][6]. High sensitivity of these nematics to different external influences especially to the magnetic field is their important peculiarity.…”
