Surfaces exhibiting superhydrophobic (SHPo) characteristics, defined by a water contact angle (CA) exceeding 150° and a sliding angle (SA) less than 10°, have garnered significant interest across both academic research and industrial applications. This is largely attributable to their unique properties including, but not limited to, oil/water separation, self-cleaning, anti-icing, and corrosion protection. The development of SHPo practical applications is predominantly constrained by factors such as the intricacy of process treatments, extended fabrication durations, the coatings involving toxic materials, and the mechanically induced alterations in surface structure. However, this study introduces a methodology that is not only simple and rapid but also environmentally friendly for the fabrication of SHPo aluminum (Al) surfaces. SHPo Al surfaces were fabricated by generating pseudo-boehmite nanostructures through boiling water treatment (BWT) and applying a minimized surface energy produced by silicone oil heat treatment (SOHT). The changing mechanism for surface morphology, surface chemistry, and surface wettability were explained by several surface analysis. Furthermore, the stability of products was evaluated after 1 month in room temperature condition and the excellent performance of the treated surface was exhibited through the self-cleaning effect, and the water bouncing effect. The present study introduces an innovative and sustainable methodology for the development of SHPo Al surfaces, paving the way for potential real-world applications.
