Contact angle — Cloth, treated to be hydrophobic, shows a high contact angle. The contact angle is the angle at which a liquid/vapor interface meets a solid surface. The contact angle is specific for any given system and is determined by the interactions across … Wikipedia
Surface energy — [ Contact angle measurements can be used to determine the surface energy of a material. Here, a drop of water on glass.] Surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created. In the physics of… … Wikipedia

Hysteresis — Not to be confused with Hysteria. Fig. 1. Electric displacement field D of a ferroelectric material as the electric field E is first decreased, then increased. The curves form a hysteresis loop. Hysteresis is the dependence of a system not… … Wikipedia
Du Noüy-Padday method — The Du Noüy Padday method is a minimized version of the Du Noüy rod replacing a large platinum ring with a thin rod that is used to measure equilibrium surface tension or dynamic surface tension at an air–liquid interface. In this method, the rod … Wikipedia
Wetting — is the contact between a liquid and a solid surface, resulting from intermolecular interactions when the two are brought together. The amount of wetting depends on the energies (or surface tensions) of the interfaces involved such that the total… … Wikipedia
