中文简介:
液晶胶体结合了液晶连续相的取向各向异性和分散的胶体夹杂物的离散排序[1,2]。液晶的长程取向排序在夹杂物之间产生结构力,这允许胶体复合物的组装用作先进的光学元件。完全地,通过使材料功能化的各种可能性(包括夹杂物和连续相)揭示了用于优化液晶胶体中光学结构的适用性和方法。在这里,我们提出了胶体颗粒和连续液晶功能化的途径。对于颗粒,显示了形状,表面结构和Janus [3]以及更高的Janus表面锚固轮廓的作用。对于散装介质,证明了手性和材料活性的作用。新型3D流动剖面显示在有源液晶单元中。可以组装胶体颗粒和活性材料流动微流体元件的限制。
课程简介: Liquid crystal colloids combine orientational anisotropy of liquid crystalline continuum phase and discrete ordering of dispersed colloidal inclusions [1,2]. The long-ranged orientational ordering of liquid crystals generates structural forces between the inclusions which allows for assembly of colloidal composites to be used as advanced optical elements. Fully, the applicability and means for optimisation of optical structures in liquid crystal colloids is revealed by the variety of possibilities for functionalizing the materials - both inclusions and the continuum phase. Here, we present routes for functionalization of colloidal particles and continuum liquid crystal. For particles, the role of shape, surface structure, and Janus [3] and higher Janus surface anchoring profile is shown. For bulk medium, the role of chirality and material activity is demonstrated. Novel 3D flow profiles are shown in active liquid crystal cells. Combining confinement of colloidal particles and active material flow microfluidic elements could be assembled.
