| 摘 要： | 基于定向静电纺丝技术制备了高取向性有序纤维薄膜, 利用有序纤维对液晶分子取向的诱导, 构建了可调制散射型偏振片. 填充混合液晶的有序聚甲基丙烯酸甲酯纤维薄膜在可见光范围内, 表现出明显的偏光特性. 混合液晶中光敏性偶氮液晶4-正丁基-4'-甲氧基偶氮苯在360 nm紫外光照射下进行顺反异构转变, 诱导混合液晶发生从各向异性到各向同性的相变. 利用混合液晶光致相变与有序纤维的耦合, 实现了薄膜偏光特性的光控切换.

| 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 ... |
