Droplet motion by Leidenfrost phenomenon on Zn plate surfaces with and without ZnO nanorods

Takuya Hirosawa et al.

Summary: Zinc oxide nanorods were prepared on Zn plates by hydrothermal processing, and the Leidenfrost phenomenon was evaluated after coating with fluoroalkyl silane. The modification decreased the Leidenfrost temperature and affected the self-propulsion of droplets on the plates, lowering both the temperature and velocity of self-propelled droplets. When ZnO-NR was formed on every other ratchet, the self-propelled droplet velocity increased with lowered temperatures for self-propulsion, exceeding the terminal velocity of Zn plates without ZnO-NR at 160 degrees C.
