Interacting liquid interfaces
Thin films areinteracting interfaces.
A thin liquid film becomes physically distinct from an ordinary liquid layer when its two bounding interfaces are sufficiently close to interact. Capillary pressure drives drainage, while hydrodynamic resistance and interfacial forces determine thinning, equilibrium thickness and eventual stability or rupture.
