同心柱筒中混合排列向列相液晶中的挠曲电效应
Flexoelectric effect of hybrid aligned nematic liquid crystals in concentric cylinders
摘要
Abstract
The director distribution of the hybrid aligned nematic liquid crystal in concentric cylinders under a radial electric field is studied.The influence of the flexoelectric effect on director distribution is mainly studied.The nematic liquid crystals are in the thin layer of concentric cylinders, in which the radial anchoring of the inner surface and the axial anchoring of the external surface, or the axial anchoring of the inner surface and the radial anchoring of the external surface constitute two hybrid aligned nematic liquid crystals models.Based on the Frank elastic theory of nematic liquid crystal, the influence of the flexoelectric effect on the director distribution in the two models is studied under the strong anchoring and weak anchoring boundary conditions by the finite-difference iterative method.The study shows that the influence of the flexoelectric effect on the director distribution is different in the inner boundary, the outer boundary and the thin layer, and that the director distribution in the thin layer is determined by the comprehensive effect of cylindrical symmetry, boundary anchoring strength, dielectric effect and flexoelectric effect.关键词
