Transient GISAXS patterns of Nafion thin films during water absorption after placement in a fully saturated water-vapor atmosphere from ambient conditions. Scattering patterns (top to bottom) were collected after 3, 16, 31 and 46 min of exposure to the saturated water-vapor environment. The films were cast on (a) Si substrates and (b) OTS passivated substrates. The patterns show the swelling of the ionomer domains during water uptake, as shown by the inward shift of the ionomer scattering ring. Reprinted with permission from Modestino et al. (2012BB86).
