Mapping between Surface Wettability, Droplets, and Their Impacting Behaviors.

Droplet behaviors on solid surfaces will influence numerous droplet-based applications ranging from nonwetting-preferred water-repellent surfaces to wetting-preferred spray coatings. Understanding droplet behaviors is complicated and centered on integrating multiple parameters that include surface properties, droplet initial states, and other boundary conditions. Previous studies have observed that droplet impacting performance by showing their underlying mechanisms is sensitive to either droplet or surface boundary conditions.
