Abstract

Deformation and fracture modes of sulfonated ionomer thin films subject to simple tension were studied. It was observed that craze stability decreased with increasing ion content up to 5 mol%. This may be due to the crosslinking produced by small ionic aggregates. The craze structures of these ionomers showed typical structural features of those of glassy polymers. At higher ion content, fewer crazes were seen, craze growth was suppressed, and localized shear deformation appeared. These changes seem to be closely related to the ionic aggregate structure, although we do not know the exact role of ionic cluster formation in deformation processes at high ion content.
