Title:
METHOD FOR PREPARING TEMPERATURE-RESPONSIVE LIGHT REFLECTING COATING AND LIGHT REFLECTING COATING
Document Type and Number:
WIPO Patent Application WO/2019/196151
Kind Code:
A1
Abstract:
Disclosed are a temperature-responsive light reflecting coating and a method for preparing same. The method involves forming a main chain cholesteric phase liquid crystal polymer by means of a polymerization reaction between an acrylate liquid crystal and an amine, and coating the main chain cholesteric phase liquid crystal polymer onto a matrix to form the light reflecting coating, wherein the acrylate comprises a chiral acrylate, and the content of the chiral acrylate liquid crystal and the degree of polymerization of the formed main chain cholesteric phase liquid crystal polymer determine the reflection wavelength of the reflecting coating. The method may further comprise subjecting the main chain cholesteric phase liquid crystal polymer to a cross-linking reaction to obtain a polymer network, thereby forming a solid coating. The preparation of the main chain cholesteric phase liquid crystal polymer merely requires a simple thermally-driven polymerization reaction, in particular a thermally-driven polymerization reaction without any catalyst.
