Abstract :
The Al surfaces are scanned with femtosecond laser pulses and the superhydrophobic surfaces are prepared. The topological and chemical changes on Al surfaces after femtosecond laser irradiation are studied. The wettability of Al surface reveals the competition between two different factors, which are hydrophilic trend due to the formation of aluminum oxides and enhanced hydrophobic trend due to increased roughness during laser pulse treatments.
