A method for enhancing the corrosion resistance of an article comprising a silver coating deposited on a solderable copper substrate is provided. The method comprises exposing the copper substrate having the immersion-plated silver coating thereon to an anti-corrosion composition comprising: a) a multi-functional molecule comprising at least one organic functional group that interacts with and protects copper surfaces and at least one organic functional group that interacts with and protects silver surfaces; b) an alcohol; and c) a surfactant.
Self-assembled monolayer of thiolated heme derivatives was formed on gold surface. The thickness of the formed monolayer and the kinetics of this adsorption were studied by surface plasmon resonance spectroscopy. This monolayer was characterized by an electrochemical method.
