Small-angle X-ray scattering (SAXS) studies of sulfonated polystyrene ionomers. I: Anomalous SAXS
Morphological studies of sulfonated polystyrenes by using small-angle X-ray scattering (SAXS) and anomalous SAXS (ASAXS) are presented. ASAXS was used to study a model ionomer system: zinc salts of sulfonated polystyrene (SPS). The results showed the presence of local clustering, as well as long-ran...

Summary: | Morphological studies of sulfonated polystyrenes by using small-angle X-ray scattering (SAXS) and anomalous SAXS (ASAXS) are presented. ASAXS was used to study a model ionomer system: zinc salts of sulfonated polystyrene (SPS). The results showed the presence of local clustering, as well as long-range inhomogeneities of ions. The observed morphology could be attributed only to the metal ionic structures, as can be proven by means of ASAXS. However, with the SAXS patterns by SPS being much stronger than those of polystyrene or SPS in acid form, the excess SAXS patterns of the metal ions can be measured with greater precision by SAXS than by ASAXS. |
