The control of surface wettability is a major challenge for many practical applications. The biomimetism of natural surfaces allowed for the deeper understanding of our fundamental knowledge of surface wettability. The consequence is the development of many methods to reproduce this phenomenon and to conceive anti-wetting surfaces from water to oil. Thus, some reviews on superhydrophobic materials were reported, showing the interest of the scientific community in this domain.

However, the elaboration of superoleophobic surfaces was reported only in few works, mainly based on a fluorinated post-treatment of rough surfaces. Indeed, the lower the surface tension of the liquid probe is, the more difficult it is to prevent spreading out. Here, we report the first example of the elaboration of superoleophobic surfaces by electrodeposition (one-pot build-up method). In order to consider the possible modulation of oleophobic behaviour, the relation between the surface properties and the electrochemical parameters is also presented.
