Title:
ANION EXCHANGE MEMBRANE HAVING AMIDE STRUCTURE, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/151512
Kind Code:
A1
Abstract:
Provided are an anion exchange membrane having an amide structure, a preparation method therefor and the use thereof. The preparation method comprises: polymerizing an aromatic hydrocarbon and a ketone having an amide structure by means of superacid catalysis, after forming the membrane by a casting method, treating the prepared membrane under alkaline conditions to obtain the anion exchange membrane having an amide structure. The obtained anion exchange membrane comprises a high-molecular polymer having an amide structure on the framework and having an excellent alkali stability. The polymer, after being subjected to an alkali treatment, not only has a high hydroxide conductivity, good mechanical properties and thermal stability, but also has an excellent alkali stability and excellent electrolytic water performance.
