Anion exchange membrane for alkaline water electrolysis and preparation method thereof

摘要

The present invention is to prepare a blend membrane of a novel poly(1-butyl-3-vinylimidazolium halide-co-styrene) copolymer (PIS) and polyvinyl alcohol (PVA), and the prepared novel imidazolium The blend membrane of ion-conducting polymer (PIS) and PVA exhibits excellent thermal stability, OH - ion conductivity, hydration properties and water electrolysis performance, so it can be applied as an anion exchange membrane for alkaline water electrolysis.
