Abstract
Certain polymer-coated solid surfaces prepared to produce an isotropic (random) planar liquid-crystal boundary condition can be rendered strongly anisotropic by exposure to orientationally ordered liquid-crystal phases. This effect reveals a plastic coupling of liquid crystal molecular orientation to hydrophobic surfaces which is absent for hydrophyilic surfaces.Keywords
