Superhydrophobic surfaces prepared by microstructuring of silicon using a femtosecond laser

Superhydrophobic surfaces exhibit contact angles with water that are larger than 150 and negligible difference in contact angle between the advancing and receding contact angles, the so-called contact angle hysteresis. In this paper, we present a novel and simple structuring process that uses intense femtosecond- laser pulses to create microstructured superhydrophobic surfaces with remarkable wetting characteristics.
