Super-hydrophobic metal surface created with femtosecond laser pulses

University of Rochester scientists have created extremely water repellent, or super-hydrophobic, materials by producing a hierarchical nano/microstructure with femtosecond laser pulses. The superhydrophobic effect is demonstrated by a falling water droplet repelled away from a structured surface with 30% of the droplet kinetic energy conserved, while the self-cleaning effect is shown by each water droplet taking away a significant amount of dust particles on the altered surface. Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing, or even in sanitation uses. Funding was provided by the Bill & Melinda Gates Foundation and the United States Air Force Office of Scientific Research.
