仿生构筑基于金属铝的超双疏表面

Self-cleaning surfaces have drawn a lot of interest for both fundamental research and practical applications. Superhydrophobic coatings with contact angles greater than 150 and roll-off angles below 10 for water have been developed, based on low-energy surfaces and roughness on the nano- and micrometer scales. However, these surfaces are still wetted by organic liquids such as surfactant-based solutions, alcohols, or alkanes.We designed an easily fabricated, transparent, and oil-rebounding superamphiphobic surface on the aluminum substrate. We also discuss the fogging test exhibits that the superamphiphobic surface had no fogging .
