Research Status of Preparation and Properties of Self-assembled Monolayers of Schiff Base on Metal Surface

Shiff bases are a class of organic compounds containing azomethine active groups-RC=N-, synthesized by the condensation of primary amine and active carbonyl. Shiff bases could form self-assembled monolayers (SAMs) through chemical adsorption on metal surface, stable and compactly arranged. SAMs are corrosion inhibition molecular films and have good corrosion resistance for the metal substrate. The methods of preparation and characterization of self-assembled monolayers (SAMs) are reviewed, the application status of the molecular modeling and topological structure in the corrosion protection are outlined, and the prospect of self-assembled monolayers (SAMs)are outlooked.
