Abstract:

We reviewed briefly the developing history of two basic concepts, surface tension and surface Gibbs free energy, in physical chemistry of surfaces, and gave a detailed discussion about the formation mechanisms of surface tension and surface free energy and the relationship between the bond energy and the surface tension. Finally, we addressed that while a surface phase could be simplified to a geometric surface, it is an actual phase which is always a metastable state owing to the surface free energy.
