[hal-01198996] Control in water adhesion of nanostructured parahydrophobic films using mesh substrates

The control in water adhesion is extremely requested for many applications in water harvesting, liquid transportation and water/oil separation, for example. Inspired by natural species such as rose petals and gecko foot, these properties can be controlled with the topography of surface structures. Here, we report for the first time the electrodeposition of sticking conducting polymers forming nanofilaments or nanosheets on textured mesh substrates. We show that the presence of mesh textures can reduce the water adhesion but it remains relatively high, which is probably due to a high amount of air between the mesh wires and a low amount on them. Moreover, it is also possible to control the water adhesion with the mesh opening or by modifying the shape of the nanostructures. This work opens new strategic ways in the control of water adhesion.
