摘要

In this paper, the inhibition performance of 2,3-Dimercapto-1-propanol (DIP) in 0.5 M sulfuric acidwere studied by polarization curves, impedance spectroscopy, scanning electron microscopy, atomicforce microscopy and theoretical calculations. The results of electrochemical experiments manifest thatDIP is a cathode corrosion inhibitor that can produce a compact protective membrane on the surface ofcopper, which can effectively reducing the corrosion current density. Field emission scanning electronmicroscope (FE-SEM) and atomic force microscopy (AFM) certificated that a conservationalmembrane was produced on the surface of the inhibited sample. In addition, the adsorption of theinhibitor was found to be consistent with the Langmuir isotherm. Molecular dynamics simulations andquantum chemical calculations were applied to elucidate the adsorption mode of inhibitor moleculeson copper surfaces.
