Title:
NOVEL POLY(SPIROBISINDANE-ARYL PIPERIDINIUM) COPOLYMER IONOMER, ANION EXCHANGE MEMBRANE, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2023/140628
Kind Code:
A1
Abstract:
The present invention relates to a technique for synthesizing a poly(spirobisindane-aryl piperidinium) copolymer having a piperidinium group introduced therein while containing a spirobisindane group in a repeating unit and having no aryl ether bond in a polymer backbone, and preparing an anion exchange membrane therefrom. A novel poly(spirobisindane-aryl piperidinium) copolymer ionomer, according to the present invention, has excellent chemical stability and mechanical properties, high ionic conductivity, improved gas permeability, and reduced mass transfer resistance. In addition, an anion exchange membrane prepared from the poly(spirobisindane-aryl piperidinium) copolymer ionomer and a composite membrane thereof have excellent chemical stability, mechanical properties, durability and water management ability, and thus can be applied to a membrane and a binder for an alkaline fuel cell, a water electrolysis device, carbon dioxide reduction, a metal-air battery, or the like.
