POLYMER LIQUID CRYSTAL EMULSION STABILIZED BY ACRYLAMIDE COPOLYMER AND LIQUID CRYSTAL COMPOSITE FILM AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A liquid crystal emulsion improved the dispersion of a liquid crystal and stabilized the dispersed liquid crystal, a polymer liquid crystal composite film and preparation method thereof are provided which prepare the composite film without using a dispersing agent by modifying a water soluble polymer used as a matrix. CONSTITUTION: A liquid emulsion for a mantic curvilinear aligned phase comprises a water soluble copolymer manufactured by polymerizing a hydrophilic monomer and from 14 to 25% by weight of one or two or more of hydrophobic monomers, from 1 to 5.5% by weight of a surface active agent and a liquid crystal such as an azomethine compound or azo compound mantic liquid crystal. The polymeric matrix can be used in manufacturing a large liquid crystal display because of its excellent electro-optical property.
