“…Recently, it has been found that the formation of microphase separation structure in membranes could improve the conductivity of AEMs (Mohanty et al, 2016;Yang et al, 2017;Han et al, 2019;Liu et al, 2019). The microphase separation and the aggregation of ionic channels were driven by the hydrophilic/hydrophobic segment of the polymer, which constructs the ionic highway for OH − conduction, shortens the pathway, and enhances the OH − conducting efficiency in membranes (Pan et al, 2014;Han et al, 2019).…”

Compared with that of proton exchange membrane fuel cells (PEMFCs), alkaline anion exchange membrane fuel cells (AEMFCs) with alkaline anion exchange membranes (AEMs) as electrolytes are attracting increased attention due to their potential use as non-precious catalysts. As one of the key components of AEMFCs, an ideal AEM must possess high hydroxide conductivity, good thermal stability, sufficient mechanical stability, and excellent long-term durability at elevated temperatures in an alkaline environment. Until now, a large number of AEMs with various chemical structures and properties have been prepared, and studied in detail, and it has been found that the microphase separation structure greatly affected the performance of AEMs. This minireview provides recent progress made of AEMs with hydrophilic/hydrophobic microphase separation structure. The hydroxide conductivity, alkaline stability, and mechanical properties of AEMs could be improved due to the formation of hydrophilic/hydrophobic microphase separation in the membranes. The relationship among the microphase separation, the chemical structure of the polymers, and the performance of membranes has been discussed in detail. This article attempts to give an overview of some key factors for the future design of novel AEMs with excellent performance such as high conductivity and improved chemical stability.

“…AEMs consist of a polymer backbone and functional cations as well as mobile anions. In recent decades, the reported polymer backbone materials for AEMs mainly include polyolefin [12,13], polyvinyl alcohol [14], chitosan [15], poly(aryl ether)s [16][17][18], polyfluorene [19], polybenzimidazole [20], poly(aryleneimidazoliums) [21], poly(ether imide) [22], Tröger's base polymer [23,24], polyarylalkyl [25,26], etc. Functional cations mainly include quaternary ammonium [27][28][29], imidazole [30,31], quaternary phosphonium [32,33], tertiary sulfonium [34], guanidine [35], metal-based cations [36,37], etc.…”

In order to effectively improve the properties of anion exchange membrane (AEM) materials, a series of novel poly(aryl ether nitrile)s with flexible side-chain-type quaternary phosphonium cations (PAEN-TPP-x) were designed and prepared on the basis of considering the influences of polymer backbone, cationic group species and the connection way between the cations and polymer chains. The synthetic method, structure and ion-exchange capacity, water absorption, swelling, hydroxide conductivity and alkaline stability of the obtained AEMs were studied. A comparative study with other reported AEMs was also performed for further exploration of the relationship between the structure and properties. These AEMs with flexible side-chain-type quaternary phosphonium cations displayed good comprehensive properties. Their water uptakes and swelling ratios were in the range of 11.6%-22.7% and 4.4%-7.8% at 60°C, respectively. They had hydroxide conductivity in the range of 28.6-45.8 mS cm -1 at 60°C. Moreover, these AEMs also exhibited improved alkaline stability, and the hydroxide conductivity for PAEN-TPP-0.35 could remain 82.1% and 80.6% of its initial value at 60 and 90°C in 2 mol L −1 NaOH solution for 480 h, respectively.
