Liquid crystal materials with ionic-surfactant operation

A conceptually new approach for developing methods of control of liquid crystals is discussed. The approach is based on modifying surface anchoring. A brief review of the authors’ research on developing ionic-surfactant control of liquid crystalline materials is described. This approach is based on the effect of electrically induced modification of the boundary conditions by ions of surface-active compounds.     

Toroidal Configuration of a Cholesteric Liquid Crystal in Droplets with Homeotropic Anchoring

JETP Letters - Orientational structures formed in cholesteric droplets with homeotropic surface anchoring have been studied by means of polarization optical microscopy and computer simulations. It...
