Superhydrophobic surfaces are fragile and are prone to failure in harsh outdoor environments. The preparation of robust superhydrophobic surfaces with stable performance and excellent properties can extend their application. In this paper, we report a simple and cost-effective method to prepare a superhydrophobic block using superhydrophobic zinc oxide powder and die pressing. The prepared sample has a contact angle of 163° and a sliding angle of 7°. Tests show that the superhydrophobic block can resist the impact of water flow, maintain its superhydrophobicity after friction or knife scraping, and quickly repair the destroyed surface by sandpaper abrasion. The sample exhibited excellent self-cleaning effect, robust mechanical property, and rapid repairability. This preparation method is also environmental-friendly and easy to operate. It will have a wide application prospect in many important fields. View Full-Text
