چکیده انگلیسی
Self-assembled monolayer (SAM) of histidine (His) was prepared on copper surface at various pH values. The effect of KI additives on corrosion protection efficiency of His SAM was also studied. The protection abilities of these films against copper corrosion in 0.5Â M HCl aqueous solution were investigated using electrochemical impedance spectroscopy and polarization techniques. The results show that the film formed on the electrode is more stable at pHÂ =Â 10 than that at other pH values. When the iodide ions were added into the His self-assembly solution (pHÂ =Â 10), protection efficiency was further improved. The inhibition mechanism has been discussed by quantum chemical calculations.
