The effects of NH 3 ‐plasma and N 2 ‐plasma treatments on rubbery polyethylene (PE) membranes on the permeation behavior for carbon dioxide (CO 2 ), O 2 , and N 2 were investigated with permeability measurements. The NH 3 ‐plasma and N 2 ‐plasma treatments on PE membranes increased both the permeation coefficient for CO 2 and the ideal separation factor for CO 2 with respect to N 2 . For O 2 transport, both the permeation coefficient for O 2 and the ideal separation factor for O 2 with respect to N 2 were increased. NH 3 ‐plasma and N 2 ‐plasma treatments on polymer membranes possibly bring about an augmentation of permeability and permselectivity simultaneously. © 2006 Wiley Periodicals, Inc.
