Molecular Orientation of Monomolecular Liquid Crystal Layers on Various Substrates

摘要: It is well known that liquid crystals will assume a specific orientation at boundary surfaces. Depending on the nature of crystal and surface, director can be oriented either perpendicular to surface (“homeotropic” alignment), parallel it (“homogeneous” or an intermediate angle (“inclined” alignment). The actual no doubt result complex interplay interface forces — electrostatic, van der Waals, steric effects, etc. work reported here attempt learn more about respective roles these forces.
