Thermodynamic discussion on Young's equation in wetting

Zeitschrift Fur Metallkunde

Young's equation is discussed on a thermodynamic basis. The result shows that the equation is a thermodynamic equilibrium of the wetting system rather than a force balance. The equilibrium satisfies the general equilibrium condition, that is, Gibbs free energy should b...
