      Cover Picture: Superoleophobic Meshes with Relatively Low Hysteresis and Sliding Angles by Electropolymerization: Importance of Polymer-Growth Control (ChemPlusChem 3/2014) (page 333)

      Dr. Thierry Darmanin, Jeanne Tarrade, Dr. Elena Celia, Dr. Herve Bellanger and Prof. Frederic Guittard

      Article first published online: 14 MAR 2014 | DOI: 10.1002/cplu.201490006

      The cover picture shows a superoleophobic stainless steel mesh obtained by electrodeposition of fluorinated conducting polymers. The inset represents an oil droplet deposited on the mesh. In their full paper on page 382 ff., Frederic Guittard and co-workers show the importance of structuring the mesh wires at a micro- and/or nanoscale while controlling the electrodeposition to avoid recovering of the mesh openings. Both the formation of structures on the mesh wires and the presence of the mesh openings are responsible of the exceptional superoleophobic properties.
