Permeation. In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. [1]

Permeation 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.
Permeation is the movement of gas and vapor through a barrier such as the wall of a bottle. It is driven by the permeant concentration gradient that always happens from the permeant’s high concentration side to the low concentration side. Fig 1.
permeation (+ adv./prep.) the process of a liquid, gas, etc. spreading to every part of an object or a place. The product's solvent, ethanol, may enhance its permeation through the skin.
Jun 8, 2024 · permeability, capacity of a porous material for transmitting a fluid; it is expressed as the velocity with which a fluid of specified viscosity, under the influence of a given pressure, passes through a sample having a certain cross section and thickness.
