Abstract: Based on ordered electrospun, membranes composed of aligned nano-fibers were obtained. By utilizing the interaction between ordered nano-fiber and nematic liquid crystals, we fabricated a novel polarized membrane with photo-tunability. In visible light region, ordered PMMA nano-fibers membrane filled with liquid crystal mixture exhibited obvious polarized properties. As the liquid crystal mixture containing azo liquid crystal can undergo transition from nematic phase to isotropic phase, polarization ability of membrane can be switched by light irradiation.

Key words: Ordered electrospun, Scattering polarizer, Azo-liquid crystal, Photo-tunable
