用圆偏振光二向色性谱法研究了3种含氨酯基的壳聚糖衍生物的胆甾液晶螺旋性质.结果表明，3种衍生物的质量分数为65%的氯仿溶液都呈现胆甾液晶相.此外，CD谱观察结果显示侧基结构对其胆甾螺旋方向有明显的影响.
We describe some relations between solitonic solutions of various models in different dimensions. We present some examples and then concentrate on some of our recent work (performed in collaboration w...
Switching Process in a Surface-Stabilized Ferroelectric Liquid Crystal Film
Surface-Stabilized Ferroelectric Liquid Crystal Film Switching Process
2010/4/15
In this paper we first discuss the operating principle of a ferroelectric liquid crystal film in the surface stabilized configuration, and then examine the switching characteristics using optical meas...
Electro-optic Response of a Polymer Dispersed Liquid Crystal Film
Electro-optic Response Polymer Dispersed Liquid Crystal Film
2010/4/19
Polymer dispersed liquid crystal (PDLC) films are potentially useful in electro-optic devices since they can be used for vision products. In this work the PDLC thin films were prepared by a photopolym...
A Mean Field Model For the Coexistence of Nematic, Smectic A and Smectic C phases in Liquid Crystals
Nematic Smectic C Smectic A Liquid Crystals
2010/4/16
We present here a mean field model for the nematic-smectic A-smectic C coexistence of a liquid crystal near the NAC point which is a multicritical point. The critical exponents calculated from our mod...
