摘要：

简述了全氟离子膜微观结构模型的研究进展，以此展开了对于全氟离子膜纳米结构研究，并详细阐述了全氟离子膜纳米结构演变的研究进展及纳米结构与离子膜离子传输能力的相关性分析。贯穿整个研究进展最重要的是微观表征技术的应用，这些技术包括广角X射线衍射 (Wide-Angle X-ray Diffraction, WAXD)、小角X射线散射 (Small-Angle X-ray Scattering, SAXS) 和小角中子散射 (Small-Angle Neutron Scattering, SANS)，以此为基础讨论了吸水率、温度、预处理等对全氟离子膜的纳米结构的影响。

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.
