Abstract：

The research progress in the microstructure model of perfluorinated ion membranes was briefly introduced, and the nanostructure of perfluorinated ion membranes was studied. The research progress in the evolution of nanostructure of perfluorinated ion membranes and the correlation analysis between nanostructure and ion transport capacity of perfluorinated ion membranes were described in detail. Throughout the whole research progress, the most important is the application of microscopic characterization techniques， these techniques include Wide-Angle X-ray Diffraction (WAXD), Small-Angle X-ray Scattering (SAXS) and Small-Angle Neutron Scattering (SANS). Based on this , the effects of water absorption, temperature and pretreatment on the nanostructure of perfluorinated ionic membranes were discussed.
