Abstract: A diselenide protective film, a method of using the diselenide protective film, and a method of making the diselenide protective film are provided. The diselenide protective film includes at least one of three novel diselenide organic polymer structures, and the film provides protection against corrosion of metals such as steel. The method of making the diselenide protective film comprising at least one of three novel diselenide organic polymer structures includes reacting a diselenide-based diamine with one of a diisocyanate, a diisocyanate and phosgene, or a diisocyanate, epichlorohydrin and potassium hydroxide.
