Recent advances in biomimetic superhydrophobic surfaces: focusing on abrasion resistance, self-healing and anti-icing

Superhydrophobic materials have been widely used in the fields of materials engineering and the coating industry due to their excellent abrasion resistance, corrosion resistance, anti-icing and antibacterial properties and have also attracted the attention of many researchers. However, in the process of application, their superhydrophobic surface is susceptible to external factors such as physical or chemical effects, resulting in the loss of low surface energy materials or the destruction of micro- and nano-rough structures, thus losing their superhydrophobic properties. This review describes the research progress in three aspects of superhydrophobic surfaces: abrasion resistance, self-healing, and anti-icing. Firstly, the definition and application of superhydrophobic surfaces, as well as the basic principle and mechanism of superhydrophobic surfaces are introduced. Then, the research status and improvement methods of superhydrophobic surfaces are presented in detail from three aspects, such as abrasion resistance, self-healing, and anti-icing. Finally, the research process of superhydrophobic surfaces is evaluated and prospected in order to provide a new perspective for the preparation of superhydrophobic surfaces with a wide range of applications and better performance.
