Abstract [en]

A nanocomposite film composed of mussel adhesive protein (MAP) and CeO2 nanoparticles has been explored as a 'green' alternative for corrosion protection of carbon steel. In this work, the nanocomposite film of sub-micron thickness was deposited on carbon steel surface by one-step-dipping method. The film was characterized by using scanning electron microscope/energy dispersive spectroscopy and atomic force microscope (AFM). The measurements of scanning reference electrode technique and in-situ AFM were performed to investigate the initial localized corrosion process at defects and self-healing ability of the nanocomposite film. The results demonstrate that the nanocomposite film possesses a certain self-healing ability and provides excellent corrosion protection for carbon steel in neutral 0.1 M NaCl solution. The self-healing ability is attributed to the functional group (catechol) of the MAP, and the healing process is explained by the fact that Fe ions released from the surface defects promote the formation of Fe-catecholato complexes in the nanocomposite film, which retards the localized corrosion at these defects.
