Abstract:

Article Preview

A facial chemical etching method was developed for fabricating stable super-hydrophobic surfaces on aluminum alloy foils. The microstructure and wettability of super-hydrophobic surfaces were characterized by scanning electron microscopy, water contact angle (CA) measurement, and optical methods. The surfaces of the modified aluminum alloy substrates exhibit superhydrophobicity, with a CA of 164.8°±1.6° and a water sliding angle of about 5°. The etched surfaces have binary structure consisting of the irregular microscale plateaus and caves in which there are the nanoscale block-like convexes and hollows.
