Abstract

Controlling droplet impact on different solid surfaces is an essential topic in developing diverse types of engineering surfaces. Slippery liquid infused porous surfaces (SLIPs) has recently been used in self-cleaning 1–3 and anti-icing surfaces . This paper introduces a new method to actively control the droplet impact on SLIPs surfaces using surface acoustic wave (SAW) technology. To do that, we designed and fabricated SLIPs on ZnO/Al thin film SAW devices. Our experimental results showed that by applying a SAW wave, the droplets' spreading, and retractions are altered, leading to a change in droplet impact regime.
