We have used the ion-track grafting technique for developing an anion exchange membrane for fuel cell applications. In order to obtain the membrane, a vinyl benzyl chloride (VBC) was grafted into an ion-irradiated poly(ethylene--tetrafluoroethylene) film. This study deals with investigation of the radicals remaining in each track and the VBC grafting with a variety of ion beams from the TIARA cyclotron. The accelerated ions with different masses and energies enabled us to clarify the effect of the LET and radial dose distribution in the track on the VBC grafting. Such extensive research will bring us interesting knowledge relating the track structures to the resulting membrane properties.
