We investigated the structure of the ethylene-co-tetrafluoroethylene (ETFE) based radiation-grafted polymer electrolyte membranes (PEMs) by the small-angle X-ray scattering (SAXS) method. From SAXS profile for the base ETFE film, a lamellar structure with spacing of 23 nm was observed. For the styrene-grafted film and PEM, the lamellar spacing measured by SAXS profiles were 30 and 33 nm, respectively. This can be explained by that the grafted regions were introduced into the amorphous phases in the lamellar structures, thereby extending the lamellar spacing.
