It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by … Visa mer The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface.

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.
