| 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包裹体的离散顺序[1,2]。液晶的远距离取向排序在夹杂物之间产生结构力，这允许组装胶体复合物以用作高级光学元件。充分地，通过使包含物和连续相材料功能化的多种可能性，揭示了液晶胶体中的光学结构优化的适用性和手段。在这里，我们介绍了胶体颗粒和连续液晶的功能化途径。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。对于散装培养基，证明了手性和物质活性的作用。在有源液晶盒中显示了新颖的3D流动曲线。可以将胶体颗粒与活性物质流微流控元件结合起来组装。 |
| 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. |
