Discotic liquid crystals as novel corrosion-resistant coatings.

A discotic liquid crystal (DLC), HBC-C12, coating was successfully applied to improve the corrosion resistance of an iron surface. The iron surface with the DLC-coating exhibited improved corrosion resistance in various environments, including exposure to air and solutions with different pH values. To the best of our knowledge, studies regarding corrosion protection using DLCs have never been reported.
