使用具有线和空间 (L&S) 图案的 SiO 2/Si 模具，通过热纳米压印技术探索了光交联液晶聚合物 (PLCP) 薄膜中的分子取向。通过偏振光学显微镜和衍射效率测量证实了分子取向结构，其中重新取向方向平行于合模线。我们演示了通过线性偏振紫外线 (LPUV) 在预对准 PLCP 薄膜上进行热纳米压印，并评估了压印 PLCP 薄膜的光学特性。结果，预先对准的 PLCP 薄膜通过热纳米压印重新定向。
Molecular orientation in a photo-crosslinkable liquid crystalline polymer (PLCP) film was explored by a thermal nanoinprinting technique using a SiO 2/Si mold with a line-and-space (L&S) pattern. A molecular oriented structure was confirmed by polarization optical microscopy and diffraction efficiency measurements, at which the reoriented direction was parallel to the mold lines. We demonstrated thermal nanoimprinting on prealigned PLCP films by linearly polarized UV (LPUV) and evaluated the optical characteristics of imprinted PLCP films. As a result, the prealigned PLCP films were reoriented by thermal nanoimprinting.
