Orientation of the dye lyotropic liquid crystals

Abstract

The orientation of some dye lyotropic liquid crystals was studied. These liquid crystals oriented homogeneously with shear force by a barcoater. The photocontrol of alignment of these liquid crystals by a thin film of a polyamide with azobenzene side chains has been developed. A patterned polarizer has given successfully by the pattern irradiation with linearly polarized light.
