Using corrosion inhibitors as thin film is one of the simplest and most widely methods in controlling the corrosion of metals. The problem is that these inhibitors can be harmful to the environment; so the research and development of green inhibitors is essential. This research examines and compares the inhibition efficiency of a green biopolymer called Zein with carbon quantum dots. Both of these inhibitors are naturally synthesized, cheap, available, renewable and can be extracted by simple methods with low cost, in addition, their waste is degradable in nature. All studies are reported on copper electrode in 3.5% sodium chloride corrosive environment. The obtained results were analyzed through electrochemical impedance spectroscopy, Tafel plots and scanning electron microscope images indicating that the coating of these inhibitors on the surface of the copper electrode was efficient enough that causes corrosion currents reduction in a few hours up to many days. Also, the results showed that higher concentrations for carbon quantum dots and lower concentrations for Zein biopolymer showed better corrosion resistance
