4-(naphthalen-1-yl) thiazol-2-amine (NTA) was synthesized and its corrosion inhibition ability on the copper was investigated. The inhibition efficiencies were evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning electron microscopy (SEM), and atomic force microscopy (AFM).The experiments were performed in various concentrations of NTA in 1 M HCl solution. Computational studies (molecular dynamics (MD) simulation and density functional theory (DFT)) were also executed. The corrosion inhibition efficiency of this compound at optimum concentration was about 90%, demonstrating that NTA is an effective corrosion inhibitor. The adsorption of inhibitor obeyed the Langmuir adsorption model.
