Title:
POLYMER-DISPERSED-TYPE LIQUID CRYSTAL FILM, EMULSION, AND METHOD FOR PRODUCING POLYMER-DISPERSED-TYPE LIQUID CRYSTAL FILM
Document Type and Number:
WIPO Patent Application WO/2021/200828
Kind Code:
A1
Abstract:
According to the present invention, provided is a PDLC film which includes a PDLC layer having excellent thickness uniformity and in which liquid crystal leakage from the PDLC layer is suppressed. A method for producing a polymer-dispersed-type liquid crystal film according to the present invention includes: forming a coated layer by coating a first transparent conductive film with an emulsion in which polymer particles and liquid crystal particles are dispersed in a solvent; drying the coated layer to form a polymer-dispersed-type liquid crystal layer containing a polymer matrix and liquid crystal particles dispersed in the polymer matrix; and laminating a second transparent conductive film on the polymer-dispersed-type liquid crystal layer, wherein the polymer particles include first polymer particles and second polymer particles, and the average particle diameter of the second polymer particles is larger than the average particle diameter of the first polymer particles.
