Bilayer molecular coatings for electrical contact improvement (BILAYER MOLECULAR COATING)

Deliverables

A new lubrication method is being developed. It consists in depositing a bounded monolayer of molecules on the substrate to be protected, and a thicker layer of molecules on top which have good affinity with the bounded monolayer. This lubrication has the advantage of being permanent, due to the bound between the substrate and the monolayer, and to the affinity between the monolayer and the top layer. Furthermore, the monolayer provides a good protection against corrosion whereas the top layer gives antiwear property. The substrates can be gold, silver, and other nobles coating. First identified applications are in the field of the electrical separable contacts, for which anticorrosion and antiwear properties are required.
