WebJan 19, 2024 · Generally, one of the CB state and the Wenzel state is metastable, and a large energy barrier exists to make the spontaneous transition to the other impossible 18,19,20,21,22,23,24,25.
Spontaneous dewetting transitions of droplets during icing
WebHowever, the equilibrium Wenzel state of a droplet is difficult to realize because it's not easy for a sessile drop to immerse its underneath microstructure completely and just in equilibrium state at the same time. Therefore, large errors occur with this method. The other scheme is to measure r value by atomic force microscope (AFM). WebOct 19, 2024 · For a highly rugged surface, the barrier from the Wenzel-to-Cassie state is much higher than from Cassie-to-Wenzel state.
