Synthesis and characterization of functional peek for ion-exchange membranes

Abstract

The sulfonated and sulfinated polyetheretherketone (SsPEEK) was prepared via a novel method. SsPEEK has two types of functional groups, the functional groups for ion-exchange and the functional groups for further strengthening of the ion-exchange membrane by cross-linking. The discussed membrane is low cost due to the use of non-expensive chemicals and simple production procedure.
