Liquid crystal light control device and method for producing the same comprising a step of emulsion polymerization of monomers of a liquid crystal resin composite |
摘要 |
In the production method of the present invention, an emulsion including a copolymer with a glass transition temperature (Tg) of −50 to 20° C. is obtained by the emulsion polymerization of a monomer group including a monomer A that is a (meth)acrylic acid alkyl ester (where the alkyl group is an open chain group with 1 to 20 carbon atoms or a cyclic group with 5 to 20 carbon atoms) as the main monomer and a monomer B having a carbon-carbon double bond and a nonionic hydrophilic group such as a polyoxyalkylene group, an amide group, and a hydroxyl group. Liquid crystals are dispersed in this emulsion, which is applied onto a conductive film-coated substrate. Another conductive film-coated substrate is laminated thereto, and thus a liquid crystal light control device is obtained. A monomer C having a carboxyl group and/or an amino group and a carbon-carbon double bond may be used in combination with a crosslinking agent so that a crosslinked structure is introduced into the copolymer. The present invention provides a liquid crystal light control device in which the transparency with a voltage applied and the shielding property with no voltage applied are compatible at high level. |
