This study deals with the ion beam irradiation effect on gas permeation properties of polyimide films. 2 MeV α, 500 keV, and 170 keV N + ions were used for modifying the membranes. It was found that there are two different effects according to the implantation dose. In the case of small‐dose irradiation, ion implantation causes a raise of permeability both for CH 4 and H 2 . When the implantation dose reaches a more important level, the implanted membranes have at the same time high permselectivity for H 2 /CH 4 and high permeability for H 2 . The relationships between the permeation properties and microstructure of the films are also discussed. © 1995 John Wiley & Sons, Inc.
