我们描述了由溶于水的染料的溶致液晶相形成的偏振膜。染料偏振器具有接近常规偏振器的高二向色比。此外，干燥的染料膜为热致变色材料提供了均匀的均匀取向。因此，薄染料膜可以同时用作内偏振器和取向剂。这些特性使得它们特别适合于基于低成本双折射塑料基板的扭曲双折射器件。
We describe polarizing films formed from the lyotropic liquid crystalline phases of dyes dissolved in water. The dye polarizers possess a high dichroic ratio close to that of conventional polarizers. In addition, the dried dye films provide a uniform homogeneous orientation for thermotropic nematic materials. Therefore, thin dye films can simultaneously serve as internal polarizers and as alignment agents. These properties make them especially suitable for twisted nematic devices based on low cost birefringent plastic substrates.
