摘要:

胆甾相液晶与各向同性流体的界面可以显示出一系列不寻常的性质,例如靠近波状界面的拓扑缺陷层。这些性质已经知道了很长一段时间,并已被探索的技术应用作为一个可调基板的胶体自组装。然而,从基本的观点来看,这种界面仍然知之甚少,甚至基本的性质,如表面张力对液晶属性的依赖性,仍然未知。在这里,我们提出了一个系统的计算胆甾各向同性界面的结构和表面张力,以及如何这些变化与液晶的属性。我们还提出了有趣的可能性润湿的界面的蓝相。

英文摘要:

The interface of a cholesteric liquid crystal with an isotropic fluid can display a range of unusual properties, such as a layer of topological defects close to an undulated interface. These properties have been know for a long time and have been explored for technological applications as a tunable substrate for colloidal self-assembly. However, from a fundamental point of view, this interface remains poorly understood and even basic properties, such as the dependence of the surface tension on the attributes of the liquid crystal, remain unknown. Here, we present a systematic calculation of the structure and surface tension of the cholesteric-isotropic interface and how these vary with the properties of the liquid crystal. We also suggest the intriguing possibility of wetting of this interface by a blue phase.
