A STUDY ON STRUCTURE OF IONIC CLUSTERS IN THE MEMBRANE OF PERFLUOROSULFONATE HOLLOW FIBER WITH SAXS
X-射线小角光散射(SAXS)研究全氟磺酸树脂中空纤维膜中的离子簇结构

The structure of ionic clustering for the membrane of perfluorosulfonate hollow fiber was studied by means of small-angle X-ray scattering (SAXS). The reflection peaks observed in the SAXS for fiber membranes at about 29 = 2° were attributed to the clustering of ions and the effects of ion-exchange capacity (IEC), cation species, water content and the drawing tensile on the diffraction peaks were investigated and discussed. The radii of the clusters and the numbers of ions in clusters were also calculated.
