Nature of the Interaction of N,N′‑Diphenyl-1,4-phenylenediamine with Iron Oxide Surfaces

Redox-active polymers and small molecules are of great interest in coatings, such as corrosion inhibitors for steel and other metals. In this work the interaction of the redox-active phenyl-capped aniline dimer (N,N′-diphenyl-1,4-phenylenediamine, DPPD) with iron oxide surfaces was investigated with the aim to understand the corrosion inhibition and self-healing properties of polyaniline and aniline oligomers on iron oxide surfaces.
