Small-Angle Scattering Study of Water-Swollen Perfluorinated Ionomer Membranes
Abstract
A structural study using both small-angle X-ray and neutron scattering (respectively SAXS and SANS) of water-swollen perfluorosulfonated ionomer (PFSI) membranes is presented. The comparison between the SAXS and SANS spectra combined with the analysis of both the scattering invariant and the Porod behavior of the scattering curves confirms the phase separation between the water pools and the perfluorinated matrix. The experimental data obtained in absolute units were analyzed in terms of the different models proposed for ionomers, and the local order model appears as the best model for describing the structure of swollen PFSI membranes. The size of the water pools and the number of ionic groups per ionic aggregate deduced from the analysis of the asymptotic behavior of the scattering curve at large angles compare well with the values deduced from the local order model. The SAXS spectra of swollen PFSI membranes are presented for the first time over an extended angular range covering 3 decades of angles using an ultra-small-angle scattering camera. The study of the small-angle upturn in intensity at very low angles revealed the existence of large-scale fluctuations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
