Color Polymer Dispersed Liquid Crystal Device with Colored Core-Shell Structure
Due to the fact the conventional polymer dispersed liquid crystal (PDLC) device operates between the transparent state and the scattering sate, color realization is limited. In this paper, we propose the color PDLC device with colored core-shell structure. By the complex coacervation microencapsulation process, liquid crystal droplets are encapsulated by the aqueous solution of gelatin, arabic gum, and color pigments. The size of the color droplet can be controlled by the pore size of the membrane filter. The average diameter of the fabricated color droplets is approximately 10 mu m.
