WebMay 2, 2024 · Dichroic dyes are usually solutions of iodine and potassium iodide. Afterwards, the dyed film is stretched to align the dichroic dyes. The higher the degree of order, the better the optical properties of the resulting polarizing film. The stretched film is brittle and easily cracked along the stretching direction after drying, and its raw ...
