| 英文摘要 | A novel approach was developed to overcome the non-uniform distribution of grafted polystyrene (PS) chains across proton exchange membranes (PEMs) manufactured using radiation induced graft polymerization of commercialized fluoropolymer films. This process involves the three key steps of grafting of styrene into fluoropolymer powder, processing the grafted powder into membranes, and then obtaining the PEM by sulfonation of these membranes. The structure of the membranes and the PEMs were analyzed by means of infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope with energy-dispersive X-ray analysis (SEM-EDX) to demonstrate the uniform distribution of poly(styrene-sulfonic acid) (denoted as PSSA) graft-chains across the PEM. The properties of the resulting PEMs, such as their ion exchange capacity (IEC), water uptake (WU), proton conductivity, dimensional stability, oxidative stability and thermal stability, were also investigated.
