A superamphiphobic surface with ordered hexagonal microstructures inspired by springtails

“…Boiling water treatment time also has a significant effect on surface wettability. After laser printing was completed, the aluminum sheet was placed in boiling water at 100 °C for 5 minutes, 24 and Al initially reacted in the water to form Al 2 O 3 · x H 2 O, and then some of the Al 2 O 3 · x H 2 O continued to react with the water to form AlO(OH) crystals, resulting in the formation of a boehmite structure. After drying the aluminum sheet, the surface becomes rough and porous with excellent micro- and nano-protruding structures, resulting in a hydrophilic surface due to the limited encapsulation of air by the nanostructures.…”
