Grafting of functionalized molecular layers onto copper, zinc, and brass

Project: PHD

Project Details


The three fundamental steps of this work are the following :
  • Preliminary conditioning of the metals (cleanings, electrochemical reduction, etc.) in order to infer to the surface a chemical affinity complementary of the -SH function.

  • Grafting of molecular monolayer onto massive metals - copper, zinc and brass (Cu63Zn37) - by self-assembly of functionalised alkanethiols : X-(CH2)n-SH with X- = (MeO)3Si- or HO- and n = 3 or 11. The nature of the solvent, the concentration and the reaction time are essential parameters to study in order to control the quality of the films.

  • The modification of the outer part of the film, by hydrolysis of the trimethoxysilanes groups of the formed monolayers from (MeO)3Si-(CH2)n-SH , or by condensation of silica precursors on HO-(CH2)n-SH layers.

The final purpose of this work is to develop thin films with good blocking and corrosion resistance properties, on one hand, and offering nice possibilities for further grafting on the outer surface, one the other hand.
