Inspired by natural species such as rose petals or Echeveria pulvinata leaves with both high water contact angle θw and high water adhesion (also called parahydrophobic), we have prepared poly(3,4‐propylenedioxypyrrole) with branched alkyl chains on the 3‐position by electropolymerization. The grafting at the 3‐position keeps the NH group free, which is an important condition to obtain nanofibers. Different lengths of branched alkyl chains are studied. Here, using extremely long branched alkyl chains (ProDOP‐br‐C10), it is possible to obtain extremely long and well defined nanofibers leading to porous surfaces (fiber mats) favoring the trapping of air between the surface and water droplets. Using a deposition charge of 200 mC cm−2, extremely high θw up to ≈ 140° while water droplets placed on this surface remained stuck even for a sliding angle of 90°, revealing extremely stron adhesion. These materials could be used in the future in water harvesting systems.

Controlo ver water adhesion is extremely necessary for many applications in water harvesting, liquid transportation, and water/oil separation, for example. Inspiredb y natural speciess uch as rose petals and gecko feet, these properties can be controlled with the topography of surface structures. Here, we report for the first time the electrodeposition of sticking conductingp olymers forming nanofilaments or nanosheets on textured mesh substrates. We show that the presence of mesh textures can reduce the water adhesion,a lthough the adhesion still remains relativelyh igh. This is probably due to ah igh amount of air between the mesh wires and al ow amount of air on them. Moreover,i ti s also possible to control the water adhesion with the mesh openingo rb ym odifying the shape of the nanostructures. This work opens news trategies for the control of water adhesion.

Postfunctionalization is a key tool for the elaboration of hydrophobic surfaces. For that purpose, the elaboration of surfaces suitable for the Huisgen reaction allows for functionalization with various hydrophobic side chains. Here the synthesis of azido or alkyne monomers is reported to prepare platform surfaces suitable for click chemistry. The surface hydrophobicity and morphology are investigated. Superhydrophobic and parahydrophobic properties are obtained depending on the starting monomer and the molecule used for the postfunctionalization. species are characterized by high θ w but also extremely high H w as observed on rose petals and gecko foot. [11][12][13] These surface properties are called parahydrophobic. [ 14 ] Usually, superhydrophobic properties are obtained by combining high surface roughness (often both of the micro and nanoscale) and low surface energy materials. [ 15,16 ] However, the water adhesion can be controlled by playing with the geometry of the surface structures or by lowering the surface energy. [17][18][19][20] In order to prepare these types of surfaces different approaches can be imagined. [3][4][5][6] It is possible to make physical or optical structuration on hard surfaces, which can be seen as a top down approach. Another option is the possibility of preparing surface starting from low molecular weight materials, which can be described as bottom-up approach. The bottom-up approach can be divided in two different strategies: the ante -and the poststrategies. Modifi cations can be added on the small molecules before the surface elaboration ( ante -strategy) or the modifi cations can be linked on the formed surfaces (poststrategy). Conducting polymers are good candidates for surfaces made with the bottom up approach. The modifi cation can be made on the monomer ( ante ) [ 21 ]
