Multicolor Polymer-Dispersed Liquid Crystal

The potential of a self‐assembled phase‐separated macroporous polymer film filled with an appropriate solvent for application in a functional multicolor polymer‐dispersed liquid crystal (PDLC) display is explored. The findings dem‐onstrate that a phase‐separated porous MMAA‐BIS polymer network filled with mixed LCs of 5CB and 5PCH can exhibit changes in structural color covering the whole visible region and an opaque milky color upon temperature variation. This system may be available for energy‐saving multicolor displays.
