such a barrier limits the adsorption rate, the dynamics are said to be 'kinetically limited'. Such energy barriers can be due to steric or electrostatic repulsions.The surface rheology of surfactant layers, including the elasticity and viscosity of the layer, play an important role in the stability of foams and emulsions.

Characterization of interfaces and surfactant layers

Interfacial and surface tension can be characterized by classical methods
