Physicists Explain Droplet Behavior on Hydrophobic Surfaces
New experiments and calculations by researchers in the UK and the Netherlands shed light on the behavior of fast-moving droplets on water-repelling surfaces, which is crucial for understanding various everyday situations, including pesticide application and disease transmission.
When a microscopic drop of water lands on a hydrophobic surface, its behavior is more complex than expected. According to Jamie McLauchlan, a PhD student at the University of Bath,
“If the droplet moves too slowly, it sticks. Too fast, and it sticks again.
This research has implications for improving aerosol and microfluidic technologies, as well as understanding the spread of airborne diseases.
