Název v původním jazyce

Hydrophilic to ultrahydrophobic transition of Al 7075 by affordable ns fiber laser and vacuum processing

Popis výsledku v původním jazyce

A lot of research efforts have been invested in the fabrication of superhydrophobic surfaces in recent years due to many protentional applications in science and industry including anti-icing, self-cleaning and anti-corrosive surfaces. The laser as a non-polluting, precise, and flexible tool can be applied to replicate surface microstructures of extremely water repellent lotus leave surface. In this study, a common nanosecond laser source is used to fabricate super/ultrahydrophobic surfaces with different microstructure designs, contact angles above 170°, and sliding angles below 5°. The freshly processed surface is hydrophilic and becomes hydrophobic and superhydrophobic in a certain time period, which could be dramatically reduced by storing samples in a high vacuum. The transformation in wetting properties is analyzed with respect to surface geometry and surface chemistry.
