| titleOfInvention | A kind of isatin aromatic hydrocarbon copolymer containing Cardo structure, preparation method and application |
| abstract | The invention belongs to the field of preparation of polymer materials and polymer ion exchange membranes, and relates to a isatin aromatic copolymer containing a Cardo structure, a preparation method and an application. The present invention carries out multi-component copolymerization reaction of isatin, 9,9-disubstituted fluorene and arene through superacid-catalyzed hydroxyalkylation polycondensation reaction, and synthesizes isatin-arene copolymer with Cardo structure and ammonium cation, which is conveniently prepared Electrolyte solution and tough anion exchange membrane, the polymerization reaction is simple and easy. The introduction of a bulky Cardo structure into the polymer can reduce its adsorption on the surface of the catalyst and improve the performance of the fuel cell; the introduction of the isatin structure can be cross-linked or functionalized to further improve chemical stability and mechanical properties. The copolymer electrolyte solution and ion exchange membrane have high ion conductivity, excellent alkali resistance/oxidation resistance and mechanical properties, and are widely used in fuel cells, energy storage batteries, electrolysis and other electrochemical devices or membrane separation related fields. |
