Spontaneous transition of a water droplet from the Wenzel state to the Cassie state: a molecular dynamics simulation study.


It is widely accepted that the superhydrophobic state is attributed to the formation of the Cassie state. The Cassie state is mostly metastable, which can be turned into the Wenzel state. Therefore, the superhydrophobic state is generally considered to be unstable. In this study, the wetting behaviors of a water droplet on different pillar surfaces are… (More)
