研究了聚合物稳定向列液晶的 Freedericksz 转变和切换动力学的临界场作为聚合物浓度的函数。提出了一个简单的唯象模型来描述观察到的临界场和动态响应时间行为作为浓度的函数。在该模型中，聚合物原纤维形成导向域，其由具有有限锚定能的“虚拟表面”界定。 (C) 2002 年美国物理研究所。
The critical field of the Freedericksz transition and switching dynamics are investigated for polymer-stabilized nematic liquid crystals as a function of polymer concentration. A simple phenomenological model is proposed to describe the observed critical field and dynamic response time behaviors as a function of concentration. In this model, the polymer fibrils form director domains, which are bounded by "virtual surfaces" with a finite anchoring energy. (C) 2002 American Institute of Physics.
