A new technique, developed by the scientists of the University of Rochester in New York, can create super hydrophobic materials out of ordinary metals just by bombarding them with laser. Without any temporary coating, these metals behave as water repellents as well as light absorbents and can be used for a variety of purposes like for making durable, low maintenance solar collectors. Hydrophobic materials are mostly made with chemical coatings but in this technique laser pulses have been used to create intricate patterns of micro- and nanoscale structures. The finding has been published in the Journal of Applied Physics.

Physicist Chunlei Guo said “This is the first time that a multifunctional metal surface is created by lasers that is super-hydrophobic (water repelling), self-cleaning, and highly absorptive.” The light absorbing property makes the material useful making solar power devices and sensors and its water...
