WebbPermeation is the process of molecular penetration of gases, vapours or fluids through the material membrane of a solid. Permeation rates are inversely proportional to the subsurface concentration. These are, in turn, affected by the thickness of the membrane, the intrinsic permeability and mass diffusivity of the material.
