ABSTRACT An efficient ultraviolet (UV) polariser based on multi-layered carbon nanotubes (CNTs) which is obtained by set of CNT films attached to substrate in series with matching orientations is demonstrated. The degree of polarisation in the UV region increases with increasing number of CNT layers, reaching ~91% in the CNT polariser with 12 layers. A thin film with photoalignment polymer exposed with more than eight layers CNT polariser induces excellent homogenous liquid crystal (LC) alignment. The fringe-field switching (FFS) LC device with the photoalignment layer shows excellent electro-optics comparable to that with conventional metallic wire-grid polariser (WGP). The work proposes cost-effective novel polariser replacing WGP for photoalignment of LC. GRAPHICAL ABSTRACT

用于液晶光配向的多层碳纳米管紫外偏振器

摘要展示了一种基于多层碳纳米管 (CNT) 的高效紫外 (UV) 偏振器，该偏振器是通过将一组 CNT 膜以匹配的方向串联连接到基板上而获得的。UV 区域的偏振度随着 CNT 层数的增加而增加，在具有 12 层的 CNT 偏振器中达到 ~91%。带有光取向聚合物的薄膜暴露于超过八层的 CNT 偏振器，可诱导出极好的均匀液晶 (LC) 取向。带有光配向层的边缘场开关 (FFS) LC 器件显示出与传统金属线栅偏振器 (WGP) 相当的优异电光性能。这项工作提出了具有成本效益的新型偏振器，以取代 WGP 用于 LC 的光对准。图形概要
