ABSTRACT
Superhydrophobic surfaces (SHSs) have possibilities for achieving significantly reduced solid–liquid frictional drag in the marine sector due to their excellent water-repelling properties. Although stability of SHSs plays a key role reduction, little consideration was given effect extreme environments on ability achieve reduction underwater, particularly when subjected acidic conditions. Here, we propose interconnected microstructures protect superhydrophobic coatings with aim enhancing environments. The armored (ASHSs) demonstrated by contact angle and bounce time droplets treated various methods, resulting an ASHS surface under environmental Additionally, inspired protecting nanomaterials from wear, spheres (ASSPs) were designed explain theoretical experimental perspectives why ASSPs can sustainable demonstrate that over 90.4% at Reynolds number 6.25 × 104 conducting water entry experiments solutions. These studies promote fundamental understanding what drives application conditions provide practical strategies maximize reduction.
