Anodic oxidation coating of aluminum impregnated with iodine compound was prepared by electrochemical method and its bactericidal activity against Escherichia coli, Staphylococcus aureus and various molds was investigated. Iodine existed as I2 in the anodic oxidation coating of aluminum and it was stipulated the iodine form iodophor having an amorphous structure. The bactericidal activity of anodic oxidation coating of aluminum impregnated with iodine compound was high against various molds and bacterial bodies. It was thought that the high bactericidal activity is due to I2 eluted from anodic oxidation coating. The anodic oxidation coating is useful as a new antimicrobial material.
