Conception de surfaces bio-inspirées à mouillabilité contrôlée à partir de polymères conducteurs

Abstract : The control of the surface wettability is a key point for the development of innovative materials in several domains such as nano-, bio- and smart-technologies. The wettability is a function of two main parameters of the materials, such as the surface energy and the surface morphology. The combination of these two parameters allows to observe wetting phenomena as super/parahydrophobicity and superoleophobicity. These extreme abilities to repel liquids with different adhesion behaviors are very interesting properties for several industrial applications. This work presents a series of polypyrrole derivatives elaborated by electrodeposition allowing to influence the parameters driving the surface wettability. Following this approach, it was possible to develop surfaces with several types of morphology and different wetting behaviors from a low to high wettability. The different functionalizations using hydrophobic compounds grafted on various preferential positions on the monomer core yielded to para and superhydrophobic surfaces showing the impact of the surface energy and morphology on the wettability. Thanks to preliminary studies, it was showed the possibility to obtain several morphologies from spherical aggregates to fibers at the micro/nano scale. Finally, this work contributes to an upstream control of the surface wettability and morphologies for many potential applications such as water harvesting, separation membranes and self-cleaning coatings.
