Provided in the present invention are a polyaryl isatin-based cationic polymer, a preparation method therefor, and the use thereof. The cationic polymer is a novel polyaryl isatin scaffold synthesized by a Friedel-Crafts polycondensation reaction under the catalysis of a superacid. An isatin structural unit in the cationic polymer possesses a very large molecular volume, which can improve the dimensional stability and mechanical properties of the cationic polymer after film formation; in addition, the N site of a cation grafted onto the cationic polymer is located on the para-position of the isatin structural unit, and such a remote grafting strategy can further improve the alkali resistance stability of the cation in the film. Therefore, the cationic polymer of the present invention exhibits extremely high ionic conductivity and mechanical and chemical stability, and can thus be used as an anion exchange membrane or an anion exchange polymer adhesive for alkaline water electrolysis, alkaline fuel cells, carbon dioxide reduction and flow batteries.
