Here, we report the possibility to obtain superoleophobic properties (contact angle sunflower oil = 150° and contact angle hexadecane = 136°) with high adhesion, by electrodeposition of conducting polymer containing short perfluorobutyl (C4F9) chains on stainless steel meshes. To obtain such properties, it is necessary to render stainless steel meshes sufficiently rough by applying a high deposition charge (Qs = 225 mC.cm-2) to deposit polymer micro/ and nanostructures around the holes of the mesh. We also show that the mesh opening is extremely important and that the best mesh opening is 100 microns (we tested from 25 microns to 800 microns). These results are exceptional with polymer containing C4F9 chains and open new strategies to design fluorinated materials with low bioaccumulative potential.
