The Pressure of the Superhydrophobic Surface under Droplet Gravity

Article Preview

Abstract:

The paper started from the most basic physical law ‘Yang-Laplace equation’, combined with the invariably characteristics of the droplet volume in the Wetting process, established a novel Gravity Model. By numerical simulated, we found that the different of the internal hydrostatic pressure of droplet affected the droplet morphology directly. Otherwise, the paper studied importantly that the droplet gravity generated the pressure on the solid-liquid interface. When the contact angle is more than 172°, the droplet is non-stability in the Cassie states. Only the droplet can keep stability in the Wenzel states.
