Abstract

The invention relates to an anion exchange membrane containing an arylene piperidine and diketone monomer copolymer as well as a preparation method and application of the anion exchange membrane, andbelongs to the technical field of alkaline water electrolyzers. The invention provides a copolymer containing arylene piperidine and diketone monomer, a main chain of the copolymer is composed of a high-molecular-weight ether-bond-free, rigid and hydrophobic aryl skeleton, piperidine cations with high alkali stability are combined, and a high-molecular-weight polymer with adjustable IEC can be prepared by copolymerization of a high-reactivity monomer diketone and the copolymer. Meanwhile, the high alkalinity of piperidine cations is retained. The obtained anion exchange membrane containing thearylene piperidine and diketone monomer copolymer has excellent chemical stability, film-forming property, conductivity and mechanical strength.
