Title:
LIQUID CRYSTAL/POLYMER COMPOSITE ELECTRICALLY-CONTROLLED SWITCHABLE FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/245736
Kind Code:
A1
Abstract:
Provided in the description is a liquid crystal/polymer composite electrically-controlled switchable film. The liquid crystal/polymer composite electrically-controlled switchable film comprises a liquid crystal material, a polymer matrix, and two layers of an ITO conductive film. The polymer matrix is sandwiched between the two layers of the ITO conductive film and is of a porous microstructure. The liquid crystal material is dispersed in the polymer matrix to form liquid crystal microdroplets, and the liquid crystal microdroplets have a vertically-oriented polymer network. The liquid crystal/polymer composite electrically-controlled switchable film has a unique composite microstructure; and in the composite microstructure, the polymer matrix of the porous microstructure endows the film with good mechanical processing performance, and moreover the vertically-oriented polymer network in the liquid crystal microdroplets further reduces the orientation difficulty of liquid crystal molecules, such that the driving voltage of the liquid crystal/polymer composite electrically-controlled switchable film is reduced, and the liquid crystal/polymer composite electrically-controlled switchable film is suitable for large-scale processing and production.
