Aniline Black coatings were obtained on Fe anodes by electrolyzing a basic solution of aniline in a water—methanol medium. Allylamine (an inhibitor of Fe corrosion), although not essential to the process, imparts better efficiency to it. The deposited polymers contain 15–20% azobenzene and exhibit semiconductor properties. The three nitroaniline isomers need a more efficient corrosion‐inhibition system. They may be polymerized to adherent films in the presence of both allylamine and K 2 CrO 4 .
