An aligned film comprises a dried mixture of a lyotropic chromonic liquid crystal material and a dopant selected from the group consisting of dyes having a molecular weight within one order of magnitude of the liquid crystal material and block co-polymers. An example of an aligned film may be transparent to visible light but not transparent to polarized light in the ultraviolet and/or infra-red portions of the electromagnetic spectrum. A method of making an aligned lyotropic chromonic liquid crystal-based film comprises providing a mixture of a lyotropic chromonic liquid crystal material and a dopant in a solvent for the liquid crystal material, applying the mixture to a substrate, and removing the solvent to produce an aligned lyotropic chromonic liquid crystal-based film.
An aligned film comprising a dried mixture of a lyotropic chromonic liquid crystal material and a dopant, wherein the dopant is selected from the group consisting of chromonic dyes having a molecular weight within one order of magnitude of the lyotropic chromonic liquid crystal material and block co-polymers.
