Abstract：Self -assembled monolayer of 3 -mercaptopropyl trimethoxysilane ( MPTS ) was fabricated on carbon-steel surface by molecular self -assembly process .Atomic force microscope ( AFM) was used to char-acterize the surface morphology of the film , while the corrosion -inhibitive properties of carbon steel were evalua-ted by potentiodynamic polarization techniques in the 0 .5 mol? L-1 HCl solution .The results show that the self-assembled monolayer of MPTS has a good inhibition performance on carbon steel , and the carbon steel surface modified by MPTS self-assembled monolayer is uniform and relatively smooth , while the surface roughness sig-nificantly reduced .In addition , the degree of hydrolysis of the silane molecules has a certain impact on the MPTS self-assembly .The SAM is more complete , and its inhibition efficiency increases with assembling time exten-ding.
