Microwave plasma modification of the surfaces of siloxane membranes (particularly lestosil and polycaibosil membranes) and acetate cellulose membranes is an example of plasma fabrication of asymmetric highly selective gas-separating polymer membranes (Arbatsky etal., 1988,1990). A schematic ofthe microwave plasma installation is showninFig. 9-34. [Pg.656]

The plasma-assisted surface modification of polymers may also serve to create permselective membranes for gas purification. For example, thin membranes of natural rubber treated with a 4-vinyl pyridine plasma are capable of separating O2 from N2 [79]. For additional information on this topic, see Ref. [80]. [Pg.49]
