The single emulsion liquid crystal (LC) droplets made by 4-cyano-4´-pentylebiphenyl (5CB, a nematic liquid crystal at room temperature) exhibit bipolar and radial orientation in aqueous solutions of polyvinyl alcohol (PVA) and sodiumdodecylsulfate (SDS), respectively. The bipolar droplets have two points of defect at the ends while the radial have one at the center. However the defect structures of its double emulsion LC droplets with different anchoring conditions have not been studied in detail. In this study, the defects in double-emulsion LC droplets with planar or perpendicular anchoring conditions at the inner and outer LC/aqueous interfaces were studied with the LC droplet produced by a microfluidic technique with flow-focused glass capillary. This fundamental study provides the information of the potential use of this LC droplets as biosensors. |
