Sustainable corrosion protection for metallic materials by Mussel adhesive protein modified lignin film

Lignin has the potential to be used as green material to inhibit the corrosion of metallic substrates. Mussel adhesive protein is used to modify lignin due to its great adhesive and film forming abilities. Electrochemical impedance spectroscopy (EIS) has been applied to in-situ measure the corrosion...
