摘要

We report on periodic, homogenous nanoripples fabricated on stainless steel (SS), copper (Cu) and aluminium (Al) substrates using an ytterbium pulsed femtosecond laser. These structures called Laser Induced Periodic Surface Structures (LIPSS) are processed at a relatively high-speed allowing us to fabricate quasi regular nanoripples in a short time over large areas. This paper investigates the effect of LIPSS on wettability behavior of SS, Cu and Al surfaces. It is shown that nanoripples significantly influenced the wettability character of these metals turning them from hydrophilic to hydrophobic behavior. The most notable behavioral change is observed for SS and Al, where strong hy-drophobicity is observed after the generation of LIPSS.
