Synthesis of copper schiff base nanocomplex as green inhibitor for 316 L stainless steel corrosion in an aggressive acidic environment.

ABSTRACT: Using inhibitors is a typical way to mitigate metal degradation by forming barriers or altering reactions. Herein, the nanocomplex of copper(II) ion with 1-((E)-(2-mercaptophenylimino) methyl) naphthalen-2-ol (H₂L) Schiff base ligand was successfully synthesized via an environmentally friendly approach using Coriandrum Sativum (CS) extract in ethanol. According to transmission electron microscopy (TEM), the average particle size of the produced nanocomplex was 12.71 nm. Using various electrochemical and physical techniques, namely, open-circuit potential (OCP), impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and SEM/EDX methods, the inhibitory effect of green Cu nanocomplex (Cu₂L₂) on the corrosion of 316 L stainless steel in a harsh mixed
