This w/w emulsion also represents a new class of polymer dispersed liquid crystals(PDLC). Traditionally known PDLC consists of oil-in-water emulsion where the oily droplet is a thermotropic liquid crystal such as 4-pentyl-4'-cyanobiphenyl (5CB), and the water phase contains certain polymers. In comparison, this water-in-water emulsion consists of Polymer-Dispersed Lyotropic Liquid Crystals, where the lyotropic liquid crystal is DSCG molecules solvated in water. Traditional PDLCs have found application, from switchable windows to projection displays. The water-in-water emulsion of polymer-dispersed lyotropic liquid crystals has the potential for building highly bio-functional materials because of its compatibility with protein structure.
