Mechanically polished copper surfaces modified with n-dodecanethiol and 3-perfluorooctyl-propanethiol

Mechanically polished copper substrates modified with ethanolic solutions (10−3 and 10−2 M) of n-dodecanethiol and 3-perfluorooctyl-propanethiol have been evaluated by X-ray photoelectron spectroscopy, contact angles and cyclic voltammetry measurements. In spite of the fact that ethanol is not necessarily the best solvent, our results show that it is possible to graft highly perfluorinated alkanethiols as well as alkanethiols on copper substrates.
