  • Encapsulated polymer stabilized cholesteric texture light shutter
    Patent number: 9835894
    Abstract: An encapsulated polymer stabilized cholesteric texture (EPSCT) light shutter is formed from a cholesteric liquid crystal and monomer that is encapsulated into micron sized, polymer-coated droplets by either an emulsification or phase separation process. The polymer-coated droplets are disposed between transparent electrodes, where they are irradiated by ultra-violet (UV) light to polymerize the monomer.
    Type: Grant
    Filed: March 9, 2016
    Date of Patent: December 5, 2017
    Assignee: Kent State University
    Inventors: Deng-Ke Yang, Yue Cui, Cuiyu Zhang
