Flow Behavior of an Oriented, Reentrant, Nematic Liquid Crystal

S. Bhattacharya, S. V. Letcher

Open full text 47 citations

Abstract

Capillary shear flow of a magnetically aligned liquid crystal was studied in the three Miesowicz orientations in the nematic, the smectic-$A$ and, for the first time, in the reentrant nematic phase. These results indicate that the flow behavior of the reentrant nematic phase is essentially identical to that of the nematic phase and can be described by the hydrodynamic theory of the nematic phase.
