Liquid crystals at interfaces

RK Gupta, V Manjuladevi - Israel Journal of Chemistry, 2012 - Wiley Online Library
The ordering in liquid crystals (LCs) can be influenced by an interface. Some of these
molecules adsorbed at the air‐water interface yield a stable Langmuir monolayer. They …

Langmuir‐Blodgett (LB) films consisting of the hybrid of a polymer having the azobenzene
(Az) side chain and 4î‐pentyl‐4‐cyanobiphenyl (5CB) are prepared. Microscopic …

Spreading and retraction dynamics of smectic liquid crystal domains at interfaces

P Viswanath, KA Suresh - Liquid Crystals, 2014 - Taylor & Francis
The spreading of a liquid drop over liquid subphase can be driven by change in interfacial
tension mediated through a surfactant, volatile solvent or photoinduced reaction. In contrast …
