This report explored a novel amphiphilic organothiol and prepared self-assembled monolayers (SAMs) on Ni substance in the aqueous micellar solution of this amphiphilic organothiol. The as-prepared amphiphilic organothiol can self-emulsify and disperse in an aqueous solution to form a stable emulsion without any additional emulsifier. The experiment shows that the self-emulsifying solution remains stable after six months at room temperature.

The growth process of passive films is comprehensively analyzed from the surface potential, microstructure and chemical composition by potential-time curve, FESEM and XPS. Meanwhile, the corrosion resistance of copper coatings with different passivation treatments is evaluated by potentiodynamic polarization curves and electrochemical impedance spectroscopy.
