Abstract

AbstractThe effects of NH3‐plasma and N2‐plasma treatments on rubbery polyethylene (PE) membranes on the permeation behavior for carbon dioxide (CO2), O2, and N2 were investigated with permeability measurements. The NH3‐plasma and N2‐plasma treatments on PE membranes increased both the permeation coefficient for CO2 and the ideal separation factor for CO2 with respect to N2. For O2 transport, both the permeation coefficient for O2 and the ideal separation factor for O2 with respect to N2 were increased. NH3‐plasma and N2‐plasma treatments on polymer membranes possibly bring about an augmentation of permeability and permselectivity simultaneously. © 2006 Wiley Periodicals, Inc.
