摘要：

Ionomer membranes, like Nafion(R) used in fuel cell, present a nanophase separation between domains with different ionic concentrations. Up to now models describe the ionic domains as spheres of about 40 Angstrom diameter. Small angles X-ray scattering studies over a large range of wave vectors, lead to a new assumption for the Nation structure, describing the polymer aggregation as elongated objects surrounding by the ionic charges.
