Effect of dichroic dye on phase separation kinetics and electro-optical characteristics of polymer dispersed liquid crystals

► Low contrast ratio and high threshold field restrict the use of PDLC devices. ► To address these problems, we incorporated dichroic dye in PDLC system. ► The addition of dye effects phase separation kinetics and morphology. ► Electro-optical performance can be enhanced by addition of a certain amount of dye.
