Current Trends in Anti-corrosion Studies of Surfactants on Metals and Alloys

The surfactants are eco-friendly, easily available, economical, and are proved to be an excellent corrosion inhibitor for metals. This review article aims to discuss and compare the reported capabilities of different surfactants against the corrosion inhibition of various metals and alloys. A variety of potential applications along with properties of diverse kinds of surfactants like non-ionic, cationic, anionic, Gemini, bolaamphiphile, and zwitterionic have been explained. Several parameters are discussed, including the influence of surfactant concentration and temperature on the process of corrosion inhibition by surfactant molecules. Method of adsorption of surfactants on the metal surface, as well as surface tension and Critical micelle concentration has also been discussed.
