Superhydrophobicity results from the combination of low surface energy materials with the surface structuration at micro and/or nanometer scale. Such surfaces are interesting because of their expected self-cleaning or anti-contamination property that could be useful in various fields such as in biomedical devices or aeronautics for example.Amongst all the developed techniques in literature to obtain superhydrophobicity, electropolymerization is a fast (deposition and structuration in one-step) and reproducible method. Moreover, electropolymerization of conducting polymers is a versatile technique. Indeed, not only the monomer chemical structure (polymerizable core, substituent)1 but also the electrochemical parameters such as doping agent, deposition charge or solvent allow to control the surface growth and their morphology in order to obtain surfaces with various water-repellent properties and even reach superhydrophobic properties.This poster focuses on the electropolymerization of poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives bearing an alkyl chain group in the 2-position and the characterization of the obtained films to reach versatile wetting surfaces.2 This work contributed to the elaboration of bioinspired surfaces with an ecotoxic-friendly approach.Figure: SEM images of PEDOT-H12 (x10000).References1) Thierry Darmanin, Frederic Guittard, J.
