Although Eqn 1.2 describes the equilibrium contact … The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique … See more The shape of a liquid–vapor interface is determined by the Young–Dupré equation, with the contact angle playing the role of a boundary condition via the Young equation. The theoretical description of contact arises from the … See more Control of the wetting contact angle can often be achieved through the deposition or incorporation of various organic and inorganic … See more • Goniometer • Meniscus (liquid) • Porosimetry • Sessile drop technique See more On the basis of interfacial energies, the profile of a surface droplet or a liquid bridge between two surfaces can be described by the Young–Laplace equation.
