各向异性分子的配向可以提供高性能的显示材料，并且可以通过使用光敏配向层来实现。相比之下，基于分子扩散的扫描波光聚合（SWaP）提供了液晶（LC）聚合物的直接取向，而不需要偏振光或光反应性染料。通过在各种模板上展示这种对齐方法以比较具有和不具有对齐层的表面条件，我们提出了一种对齐LC的方法，无论表面处理如何，即使在表面摩擦的相反方向上，也表明SWaP能够实现稳健且容易的分子对齐。(c)2019日本应用物理学会。
Alignment of anisotropic molecules can provide high-performance display materials, and can be achieved by using a photoresponsive alignment layer. By contrast, scanning wave photopolymerization (SWaP) based on molecular diffusion offers direct alignment of liquid crystal (LC) polymers without the need for polarized light or photoreactive dyes. By demonstrating this alignment method on a variety of templates to compare surface conditions with and without alignment layers, we present a process to align LCs regardless of surface treatment, even in the opposite direction of surface rubbing, indicating that SWaP enables robust and facile molecular alignment.
