英文摘要	Inhibiting effect of the novel gemini surfactant on copper was investigated in 3.5% NaCl solution using weight loss and electrochemical measurements. Presence of inhibitor and increase of concentration greatly decrease corrosion rate, parameters determined from polarization curves and EIS plots show that inhibitor decreased both cathodic and anodic current densities, suppressed charge transfer process by adsorption on copper surface. Thermodynamic calculation indicates chemisorption obeys the Langmuir adsorption isotherm. Quantum chemical calculation reveals that inhibitor molecules suppress copper corrosion via formation of N-Cu complex. Relationships between inhibition efficiency and molecular orbital were also evaluated.
