Polymeric membranes

From Wikipedia, the free encyclopedia

Polymeric membranes are membranes that take the form of polymeric interphases, which can selectively transfer certain chemical species over others. There are several mechanisms that could be deployed in their functioning. Knudsen diffusion and solution diffusion are prominent mechanisms. Polymeric membranes are of particular importance in gas separation applications. Key industrial applications include: oxygen-nitrogen separation, removal of organics and natural gas enrichment.
