通过局部光诱导原位聚合一步形成红外反射微片

反射率可调的液晶智能窗已逐渐应用于绿色和智能建筑材料中以满足节能需求，但其基本缺陷限制了其应用。在本研究中，我们发展了一种局部光诱导原位聚合的方法，以快速制备出具有红外反射功能的液晶聚合物微片。除了LC配方，光掩模，液晶盒，阻聚剂和制备条件进行了专门管理，以控制原位聚合的程度，即微片形态。精确地获得圆形、三角形和椭圆形的微片，并且微片略大于光孔。这种简单、可控、连续和可回收的技术有望推动具有可调反射带和状态的高质量LC智能窗的产业化。
Liquid crystal (LC) smart windows with adjustable reflectivity have been gradually applied in green and intelligent building materials for energy saving needs, but their applications are limited by their fundamental defects. In this study, we developed local photo-induced in situ polymerization to rapidly fabricate the infrared reflection microsheets of a cholesteric LC polymer as functional units. With the exception of the LC formula, the photo mask, liquid crystal cell, polymerization inhibitor, and the preparation conditions were specifically managed to control the extent of in situ polymerization, namely the microsheet morphology. The circular, triangular and oval-shaped microsheets were precisely obtained and were slightly bigger than the light hole. This easy, controllable, continuous and recyclable technology is expected to promote the industrialization of a high quality LC smart window with an adjustable reflection band and state.
