For flexible displays, there is a desperate need for a broadband coatable polarizer that can absorb light in a specific direction. Conventional polarizers fabricated by the polymer stretching process are too thick (50-200 μm) to be used as polarizers that can be applied to antireflective films in flexible displays. For the development of the broadband coatable thin film polarizer, diacetylene (DA) amphiphiles containing I or I are newly designed and synthesized, and the content of DA amphiphiles in the 4,6-decadiyne solvent is optimized to form a lyotropic liquid crystal (LLC) phase. Topochemical polymerization of uniaxially oriented iodine-based DA not only stabilizes the film but also broadens the polarization light region from 350 to 700 nm. The transfer and amplification of iodine and DA functions in uniaxially oriented thin films enable the fabrication of broadband coatable thin film polarizers.
对于柔性显示器而言，迫切需要一种能够在特定方向吸收光的宽带可涂布偏振器。通过聚合物拉伸工艺制造的传统偏振器太厚（50-200μm），无法用作可应用于柔性显示器抗反射膜的偏振器。为了开发宽带可涂布薄膜偏振器，新设计并合成了含碘或含I的二乙炔（DA）两亲物，并优化了4,6-癸二炔溶剂中DA两亲物的含量以形成溶致液晶（LLC）相。单轴取向碘基DA的拓扑化学聚合不仅使薄膜稳定，还将偏振光区域从350nm拓宽到700nm。单轴取向薄膜中碘和DA功能的转移和放大使得能够制造宽带可涂布薄膜偏振器。
