Dithiocarbamate modified glucose(DTCG),an environment-friendly corrosion inhibitor,has been synthesized. Corrosion inhibition effect of DTCG self-assembled monolayers(SAMs) formed on copper surface was measured in 3% NaCl solution using electrochemical impedance and polarization curve methods. The results indicate that DTCG SAM has good corrosion inhibition effect for copper and its inhibition efficiency can be close to 97% after self-assembling in 120 mg/L DTCG for 4 h. Quantum chemical calculations also show that DTCG possesses excellent anticorrosion performance.
