Recent advances in the potential applications of bioinspired superhydrophobic materials

International audienceThis review allows to give an overview of recent advances in the potential applications of superhydrophobic materials. Such properties are characterized by extremely high water contact angle and various adhesion properties. The conception of superhydrophobic materials has been possible by studying and mimicking natural surfaces. Now, extremely various applications have emerged such as anti-icing, anti-corrosion and anti-bacteria coatings, microfluidic devices, textiles, oil/water separation, water desalination/purification, optical devices, sensors, batteries and catalysts. At least two parameters were found to be essential for application: the presence of air on superhydrophobic materials with self-cleaning properties (Cassie-Baxter state) and the robustness of the superhydrophobic properties (stability of the Cassie-Baxter state). This review will allow to researchers to envisage new ideas and to industrialists to advance in the commercialization of these materials
