A novel polyfluorene-based ionomer, an anion exchange membrane and method for preparing the same

摘要

The present invention relates to a novel polyfluorene-based polymer ionomer, an anion exchange membrane, and a method for preparing the same, wherein an aromatic polyfluorene-based polymer ionomer in which a piperidinium group is introduced in a repeating unit without an aryl ether bond in a polymer backbone is synthesized; By manufacturing an anion exchange membrane from this, it has excellent thermal and chemical stability and mechanical properties, and has high ionic conductivity, so it can be applied to membranes for alkaline fuel cells and binders or water electrolysis.
