  • Liquid crystal capsule and method for producing the same
    Patent number: 10441936
    Abstract: Shown is a method for producing a liquid crystal capsule having a particle diameter of 30 to 150 nanometers, and a method for producing a liquid crystal capsule without using a homogenizer. The disclosure concerns a method for producing a liquid crystal capsule, including a step of preparing an emulsion by performing phase inversion emulsification of a mixed material obtained by mixing a liquid crystal composition, a monomer, a surfactant, and a polymerization initiator; and a step of producing a liquid crystal capsule by applying a coacervation method to the emulsion. The disclosure also concerns a liquid crystal capsule having a liquid crystal composition, a surfactant and a capsule wall, wherein the capsule wall has a closed curved shape, the liquid crystal composition and a hydrophobic moiety of the surfactant are arranged inside the capsule wall, and a hydrophilic moiety of the surfactant is arranged outside the capsule wall.
