One-pot method for build-up nanoporous super oil-repellent films.
The aim of this work was to demonstrate the possibility of obtaining super-surfaces, i.e. superoleophobic and as a consequence superhydrophobic properties, from electrodeposited conductive polymer. From original structure containing a fluorinated chain grafted to 3,4-ethylenedioxypyrrole (EDOP) core, we report the characterization of the electrochemical properties of polymer films as well as the morphology (SEM) and wettability against probe liquids (water, diiodomethane, hexadecane). The exceptional oil-repellent properties, quickly obtained and in one step, are in correlation with the nanoporous structures of the films which is of great interest in the development of lyophobic materials based on the fluorophobic effect.
