Abstract

The self-organization of ferroelectric columnar liquid crystals (FCLCs) is demonstrated. Columnar order is spontaneously formed in thin films made by the wet-process due to its liquid crystallinity. Electric-field application results in high optical quality and uniform spontaneous polarization. Such good processability and controllability of the wet-processed FCLC films provide us with potential organic ferroelectric materials for device applications.

摘要

展示了铁电柱状液晶（FCLC）的自组织现象。由于其液晶性，湿法制得的薄膜中会自发形成柱状有序结构。在外电场作用下，薄膜会呈现出高质量的光学各向异性和均匀的自发极化。湿法制 FCLC 薄膜具有良好的加工性和可控性，为器件应用提供了有潜力的有机铁电材料。
