Domain spacing, nafion, SAXS  Ion-conductive membranes used in
energy devices are always under compression to minimize a
device's contact resistance. In this paper, the conductivity and
nanostructure of Nafion membrane, a commonly used ionomer in
many electrochemical energy applications, are investigated under
compression. Hydrophilic-domain spacing as a function pressure
is determined both in the plane (face-on imaging) and thickness
(edge-on imaging) directions using small-angle X-ray scattering
(SAXS). SAXS results suggest a similar nanostructure in all
directions indicating la
