Document Type and Number:
WIPO Patent Application WO/2021/046994
Kind Code:
A1
Abstract:
Disclosed are a polymer dispersed liquid crystal composition, a method for preparing a polymer dispersed liquid crystal film, and a display panel. The polymer dispersed liquid crystal composition comprises a polymer monomer and a liquid crystal molecule, wherein the polymer monomer is a fluorine-containing polyimide monomer bonded to polyaniline by chemical bonds, comprising a polycondensation unit of a fluorine-containing dianhydride monomer and a fluorine-containing diamine monomer. Conductive polyaniline is introduced into the fluorine-containing polyimide monomer by chemical bonds to improve the conductivity of the polyimide monomer, thereby obtaining a polymer dispersed liquid crystal film having a driving voltage of less than 30 V and having both an excellent insulation performance and resistance to irradiation.
