- Abstract
Due to the construction of complicated micro-/nanohierarchical structures, designing durable superamphiphobic Al surfaces by a simple, environmentally friendly, and fast method remains a great challenge. In this article, we used a simple and environmentally friendly technique that includes laser marking and water boiling treatment to create triple-scale micro-/nanostructures on 1060 Al surfaces. The as-prepared 1060 Al surfaces revealed excellent superamphiphobicity with low sliding angles, owing to great Cassie state stability after 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS-17) modification. The contact angle of the water droplets reaches 160°, and that of peanut oil droplets reaches 155° on this surface. Meanwhile, this superamphiphobic Al surface also possesses excellent self-cleaning ability and oil resistance. Even when entirely immersed in oil sludge, the as-prepared Al surfaces can retain superamphiphobicity. Furthermore, the as-prepared superamphiphobic Al surface demonstrates outstanding chemical stability and endurance in a variety of application environments. In addition, the as-prepared superamphiphobic Al surface offers potential anti-icing and anti-frosting properties. Therefore, the as-prepared superamphiphobic Al surface will be a potential candidate with broad applications in aerospace, construction, and marine industries.
