چکیده انگلیسی
Inositol hexaphosphate (IP6) was proposed as an environmentally friendly reagent to prevent metal surface from corrosion through a self-assembled monolayers (SAMs) method. In situ surface enhanced Raman scattering (SERS) spectroscopic investigations revealed that the self-assembling of IP6 at the roughened copper surface in a Na-salt phytic acid solution took two steps involving firstly self-cleaning the surface and then forming IP6 monolayers. The features of the IP6 monolayers were evaluated by the time-dependent Raman spectroscopic measurement, Raman mapping and electrochemical polarization experiments. Based on the calculation results for vibration spectrum of IP6 molecule with PM3 method, a model for IP6 molecule adsorbed chemically on the roughened copper via two co-planar phosphate moieties was suggested. The copper surface with the IP6 monolayers presents the inhibiting action in a 0.1 mol Lâ1 KC1 solution but the relative inhibition efficiency is of 41.2% because of the water co-adsorption.
