Recently, perfluorocarboxylic acid ion exchange resin, as the core material of high-end ion exchange membranes, has attracted much attention in the green upgrading of new energy and chlor-alkali industry. With excellent ion conductivity, chemical stability and heat resistance, it has become a key support for hydrogen fuel cells, water electrolysis for hydrogen production and green transformation of chlor-alkali industry, known as the "golden core". Its synthesis takes the precise copolymerization of tetrafluoroethylene and functional monomers as the core, and achieves dual improvement of ion exchange capacity and mechanical strength through post-treatment such as alkaline hydrolysis, acid transformation and overpressure enhancement composite. The industry implements strict quality control through infrared, NMR, GPC, thermal analysis and other methods to ensure key indicators such as ion exchange capacity and thermal stability meet standards. At present, the global high-end market is still dominated by international giants. China is making breakthroughs in process greening, characterization intelligence and application customization to help the independent control of clean energy industry.
