Fabrication of a Highly Stable Superhydrophobic Surface with DualScale Structure and Its Antifrosting Properties Qinghua Zhang,* Biyu Jin, Bing Wang, Yuchen Fu, Xiaoli Zhan,* and Fengqiu Chen College of Chemical and Biological Engineering, Zhejiang University, Hangzhou 310027, China ABSTRACT: The stable superhydrophobic aluminum alloy surface with dual geometric architectures was prepared by a combination of simple processes of chemical etching, dip-coating, and modification of fluorosilicone. The Al surface with 20 min of acid etching and nanosilica dip-coating has the best superhydrophobicity, which showed water contact angles (WCAs) of >157° and water sliding angles (SAs) of
