Crystal size shrinking in radiation-induced crosslinking of polytetrafluoroethylene: Synchrotron small angle X-ray scattering and scanning electron microscopy analysis

SAXS curves of PTFE (a), XPTFE-150 (b), XPTFE-500 (c), XPTFE-1000 (d), XPTFE-3000 and (e), Scattering intensity decreased with an increase of dose in Fig. It indicates that the content of lamellae decreases as the radiation increases.
