Recent advances in self-healing superhydrophobic coatings

Due to special surface wettability, biomimetic superhydrophobic materials have received a lot of attention. Nevertheless, its short useful life hinders widespread application. To fabricate long-life superhydrophobic coatings, researchers have optimized material selection and preparation techniques. On this basis, endowing the superhydrophobic coating with self-healing characteristics will further extend its useful life. This paper reviews the recent progress in current research on self-healing superhydrophobic coatings. We mainly describe the mechanism and classification of self-healing superhydrophobic coating. Given the common problems of selfhealing superhydrophobic coatings, such as the healing efficiency, healing times, and healing universality, the existing solutions are summarized and the views are put forward. Then the applications of self-healing superhydrophobic coatings are summarized. Finally, the prospects of self-healing superhydrophobic coatings prospect.
