摘要

液晶(LC)相因其刺激响应特性而被用于各种自组装技术。特别是表面上和表面中的取向控制液晶结构,在物理学、化学和材料科学领域得到了广泛的研究,因为它们可用于传统液晶显示之外的图案化应用。近期发展的关键思路是控制基底和低浓材料之间的表面锚定条件。具体来说,液相色谱相中的缺陷已被引入作为一种有效的光刻工具,用于制作杰出的图案。本综述概述了液相色谱材料的主体结构和表面诱导结构,以说明基底表面特性与液相色谱材料弹性特性之间的关系。两大主题是:(1) 取向控制,可通过使用固体和流体基底进行微米和纳米压制来实现;(2) 低浓材料在光电和传感器方面的应用。最后,综述讨论了在柔性基底上制造的液相色谱材料的缺陷结构及其可能的应用。

Surface-induced orientation of liquid crystal phases

Liquid crystal (LC) phases have been used in various self-assembly technologies owing to their stimuli-responsive characteristics. Especially, orientation-controlled LC structures on and in surfaces are extensively studied in physics, chemistry, and materials science because they can be used in patterning applications beyond the conventional LC display. The key idea in recent development is to control the surface anchoring condition between the substrate and LC materials. Specifically, defects in the LC phases have been introduced as an effective lithographic tool for fabricating distinguished patterns. In this review, the bulk and surface-induced structures of LC materials are overviewed to show the relationship between the surface characteristics of the substrates and the elastic properties of LC materials. The two main themes are (1) orientation control, which can be achieved by micro- and nano-confinement using solid and fluid substrates, and (2) the application of LC materials as optoelectronics and sensors. Finally, the review discusses the defect structures of LC materials fabricated on flexible substrates and their possible applications.

期刊介绍: Giant is an interdisciplinary title focusing on fundamental and applied macromolecular science spanning all chemistry, physics, biology, and materials aspects of the field in the broadest sense. Key areas covered include macromolecular chemistry, supramolecular assembly, multiscale and multifunctional materials, organic-inorganic hybrid materials, biophysics, biomimetics and surface science. Core topics range from developments in synthesis, characterisation and assembly towards creating uniformly sized precision macromolecules with tailored properties, to the design and assembly of nanostructured materials in multiple dimensions, and further to the study of smart or living designer materials with tuneable multiscale properties.
