Fluorine-free laser-textured superhydrophobic surfaces on 3003 aluminum alloy
3003 aluminum alloy is widely used in heat exchangers and new energy vehicle battery casings, but its hydrophilic surface is susceptible to water accumulation, fouling, and icing. In this study, a fluorine-free bioinspired superhydrophobic surface was fabricated on 3003 aluminum alloy by nanosecond laser texturing foll...
