We demonstrate anisotropic optical films based on liquid crystalline polymer (LCP) using a capillary force lithography (CFL). The fabricated optical films can be used as both an optical component and a self-aligning capability of liquid crystal molecules introduced on the film. Additionally, HA or PA LC can be induced on same material by controlling the water repellency of LCP surface. Moreover, surface anchoring transitions could be controlled by variation of pattern sizes and surface treatment. In this point of view, one thin optical film can act both retarder and alignment layer and then shows good retardation, LC alignment, and transmittance at the same time.
我们使用毛细作用力光刻（CFL）展示了基于液晶聚合物（LCP）的各向异性光学膜。所制造的光学膜不仅可用作光学元件，还可用作引入膜上的液晶分子的自对准能力。此外，通过控制 LCP 表面的疏水性，可以在相同材料上诱导 HA 或 PA LC。此外，可以通过改变图案尺寸和表面处理来控制表面锚定转变。从这个角度来看，一个薄的光学膜可以同时充当延迟器和对准层，从而同时显示出良好的延迟、液晶对准和透过率。
