染料掺杂聚合物分散液晶（PDLC）是一种应用于智能窗的有吸引力的材料。使用PDLC的智能窗户可以简单地操作，并且与采用光致变色或热致变色材料的其他设备相比具有高对比度。然而，在常规染料掺杂的PDLC方法中，染料污染会引起问题，并且限制了电动智能窗的商业化程度。在这里，我们报告的方法来解决染料相关的问题，通过封装在单分散胶囊的染料。通过封装，所制造的染料掺杂的PDLC在600 μ m下具有>120的对比度。这种将染料封装在染料掺杂的PDLC器件中的核壳结构微胶囊中的制造方法为基于染料掺杂的PDLC的智能窗提供了实用的平台。
A dye-doped polymer-dispersed liquid crystal (PDLC) is an attractive material for application in smart windows. Smart windows using a PDLC can be operated simply and have a high contrast ratio compared to those of other devices that employed photochromic or thermochromic material. However, in conventional dye-doped PDLC methods, dye contamination can cause problems and has a limited degree of commercialization of electric smart windows. Here, we report on an approach to resolve dye-related problems by encapsulating the dye in monodispersed capsules. By encapsulation, a fabricated dye-doped PDLC had a contrast ratio of >120 at 600 urn. This fabrication method of encapsulating the dye in a core shell structured microcapsule in a dye-doped PDLC device provides a practical platform for dye-doped PDLC-based smart windows.
