摘要：The thermal properties of perfluorosulfonated ionomer (PFSI) precursors, H-type, and Na-type PFSIs with various ion exchange capacity of 0.36, 0.88, 1.02, and 1.20 mequiv./g in the form of pellets were investigated by thermogravimetry and differential scanning calorimetry. It is revealed that the Na-type PFSIs have the highest thermal stability, and the mechanism of thermal degradation of H-type PFSIs is different from those of precursors and Na-type PFSIs. The DSC measurements indicate that the thermal behaviors of the precursors, the H- and Na- type PFSIs are very different due to the difference of the end groups of the pedants.
