Abstract
The formation of a film composed of two layers on gold substrates (evaporated and electrodeposited) is reported. The bilayer film is constituted of a monolayer of n-2-perfluorohexyl-ethanethiol (F6H2) molecules bound to the metal surface and a supernatant lubricant film (PFPE) in which F6H2 molecules are present. One- and two-step deposition modes of the bilayer film are considered and the corresponding films are characterized by X-ray photoelectron spectroscopy. The results confirm the formation of a monolayer in both processes used, but it appears that the quality of the bilayer film is better in the case of the one-step process. Furthermore, the lubricant film containing F6H2 has the potential of self-healing the metal/bilayer interface.Keywords
