摘要：

The structure of perfluorinated ionomer membranes (Nafion(R)) incorporating large organic cations, tetraethylammonium (TEA(+)) and 1,1'-dialkyl-4,4'-bipyridinium cations (CnV2+, n = 3 and 8), is studied using small-angle X-ray scattering (SAXS). For TEA(+) and C3V2+-form membranes, the SAXS maxima show the presence of the ionic clusters as large as those for Na+-form (ca. 4 nm in diameter). For C8V2+-form membranes, the intercluster distance expanded to a value larger than that for H+-form after the ion-exchange reaction for 5 days. However, the water content and cluster size decreased significantly after the ion-exchange reaction for 50 days or boiling treatment.
