摘要

The interaction mechanism of 2, 5-dimercapto- 1, 3, 4-thiadiazole (DMTD) on copper surface was studied by surface-enhanced Raman scattering (SERS), infrared (IR) and X-ray photoelectron spectroscopy (XPS) techniques. The SERS spectra were obtained. We found that DMTD bound With the copper via its two-excocyclic mercapto groups. The Monosulphide salt was formed. At the same time, DMTD Coordinated with the Cu ion through the excocyclic mer- Capto groups and polymerized via the Cu ion into a one - Dimensional polymer chain on the copper surface.
