Abstract
The present work proposes a simple, scalable, and economical route for producing superhydrophobic surfaces using thermomechanical and microwave-assisted hydrothermal treatments. Infusing dopants (Mg, Fe) during thermomechanical processing resulted in a distinct and denser nanostructures on aluminum surface. The silanization of these surfaces resulted in superhydrophobicity (θa > 160°) with low hysteresis (≈ 2°) and adhesion (≈ 25 µN) compared to un-doped surface. The reduction in pitch between nanostructures enhanced capillary pressure (> 900 kPa), stabilizing Cassie state and restricting three-phase line sagging. The present work highlights the importance of doping in enhancing the durability of nanostructures for improving de-wettability.
