摘要：

2,5-Dimercapto-1,3,4-thiadiazole (DMTD) monolayer was self-assembled on the fresh copper surface to form protective monolayer against copper corrosion in acidic solution. Its corrosion inhibition was investigated in 0.5 M HCI by cyclic voltammetry, potentiodynamic polarization and electrochemical impedance spectroscopy methods. The results revealed that the DMTD monolayer inhibited the copper corrosion effectively with the optimum self-assembly time of 10 h and the optimum self-assembly concentration of 7.5 mM. Surface observation was performed using scanning electron microscope, contact angle goniometer and Fourier transform infrared spectrometer. The molecular simulation has been used to simulate the adsorption model of DMTD molecule on Cu(1 1 1) surface. (C) 2010 Elsevier Ltd. All rights reserved.
