A chromonic liquid crystal (CLC) thin film polarizer was fabricated by coating the self-assembly of lyotropic CLCs and the successive photo-polymerizing processes. Their molecular packing structures and optical behaviors were investigated from using the combined techniques of microscopy, scattering and spectroscopy. To stabilize the oriented Sunset Yellow FCF (H-SY) films and to minimize the possible defects generated during and after the coating, acrylic acid (AA) was added and photo-polymerized. The polymer-stabilized H-SY films showed good mechanical and chemical stabilities without sacrificing a high polarizability. Additionally, patterned polarizers were fabricated by applying a photomask during the photo-polymerization of AA, which may open new doors for the practical applications in electro-optic devices. This work was mainly supported by the Human Resource Training Project for Regional Innovation and BK21 PLUS Program, Korea. |
