    • The present invention comprises a device and method for ordering molecules of lyotropic chromonic liquid crystals to aligned structure of a dried film. An example of an aligned film may be transparent to visible light but not transparent to polarized light in the ultraviolet and/or infrared portions of the electromagnetic spectrum. A shearing device having a shearing tool and a repelling pad may repel the solvent and provide a shear force to shear the LCLC dissolved in the solvent as a film on the surface of a substrate. A method of making an aligned lyotropic chromonic liquid crystal-based film comprises providing a mixture of a lyotropic chromonic liquid crystal material in a solvent for the liquid crystal material, applying the mixture to a substrate, shearing the lyotropic chromonic liquid crystal with a shearing device and removing the solvent to produce an aligned lyotropic chromonic liquid crystal-based film.
    • 本发明包括用于排列溶致性发色液晶分子的装置和方法,以使干膜的对准结构。 取向膜的实例可以对可见光透明,但对电磁光谱的紫外线和/或红外部分的偏振光不透明。 具有剪切工具和排斥垫的剪切装置可以排斥溶剂并提供剪切力以将溶解在溶剂中的LCLC作为膜在基材的表面上。 制造排列的溶致色发液晶基膜的方法包括在液晶材料的溶剂中提供溶致色发色液体材料的混合物,将该混合物施加到基材上,用剪切装置剪切溶致性发色液晶 并除去溶剂以产生排列的溶致发色液晶基膜。
