Synthesis of novel perfluorosulfonamide monomers and their application

The novel perfluorosulfonamide monomers and their preparation methods have been developed. The ternary-copolymer membranes, utilizing the perfluorosulfonamide monomers as the cross-linking site, can be efficiently converted to the cross-linked membranes with the strictly controlled structure. The novel cross-linking method has proved to be effective for the improvement of the mechanical properties at high temperature, while keeping its high proton conductivity.

The synthesis of the novel perfluorosulfonamide monomers, their ternary-copolymers and their perfluorosulfonimide-cross-linked membranes are reported. Figure optionsDownload as PowerPoint slide
