    Abstract

    Low cost nanosecond lasers can be used to fabricate various micro and nanostructures on metal surfaces. After chemical modification, superhydrophobic surfaces with different water adhesion are obtained. However, only few studies are reported on the droplet impact performance of these superhydrophobic surfaces. Therefore, we investigate the droplet impact performance of the typical superhydrophobic surfaces fabricated by nanosecond laser with different pulse duration. Results indicate that the superhydrophobic surfaces fabricated by different pulse duration nanosecond lasers exhibit extremely short solid-liquid contact time when droplets are impacted. Under the same parameters, superhydrophobic surface fabricated by shorter pulse duration laser has higher microstructures, which results in an increase in the solid-liquid adhesion force during droplet impact and a relatively long solid-liquid contact time.
