Permeation level
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. Permeation is modeled by … Zobraziť viac The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high … Zobraziť viac Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and stored them under water.

WebPermeation is the movement of a gas or vapor through a semi-permeable barrier such as the wall of a film, whole package, medical device, or even a flexible electronic display. The gas or vapor is driven to move from an area of high concentration to an area of low concentration. Modern packaging materials are made from a variety of materials ...
