An Overview of Membrane ScienceAuthor(s): Jennifer Stewart
Membranes have become increasingly significant in chemical technology, and they are being used in a wide range of applications. The capacity of a membrane to control the permeability of a chemical species in contact with it is a key attribute that is used in every application. In most packaging applications, the goal is to entirely prevent penetration. The purpose of controlled drug delivery is to slow the rate at which a drug passes from a reservoir to the body. The purpose of separation applications is to allow one component of a mixture to readily permeate the membrane while preventing other components from doing so. Membrane science has evolved from a laboratory curiosity to a widely used technology in industry and medical since the 1960s. This trend is anticipated to continue, especially in the areas of membrane gas separation and pervaporation separation.
