Fabrication of Microcapsules for Dye-Doped Polymer-Dispersed Liquid Crystal-Based Smart Windows
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 nm. 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
