6 FAQs about [Energy storage ion exchange membrane]

What are ion exchange membranes?

1. Introduction Ion exchange membranes (IEMs) are typically composed of hydrophobic substrates, immobilized ion-functionalized groups, and movable counter-ions. Depending on the type of ionic groups, IEMs are broadly classified into cation exchange membranes (CEMs) and anion exchange membranes (AEMs).

How can ion exchange membranes be improved?

Further exploration and optimization of operating conditions are essential to achieve precise control in structure and composition of improved ion exchange membranes. Along with the advancements of materials and preparation methods for ion exchange membranes, the corresponding applications have also made rapid progress.

What are ion exchange membranes (IEMs)?

Depending on the type of ionic groups, IEMs are broadly classified into cation exchange membranes (CEMs) and anion exchange membranes (AEMs). Naturally, the ion-functionalized groups attached onto the IEMs will dissociate after the penetration of sufficient water molecules, releasing cations or anions for the transfer of corresponding ions.

Are porous ion exchange membranes a good choice?

Porous ion exchange membranes from polymers of intrinsic microporosity and Troger's Base as well as porous fillings such as metal-organic framework, and covalent organic framework also deserve special attention, as these may achieve extremely high separation efficiency and beat the “trade-off” effect in IEMs-based process.

How can ion exchange capacity be controlled?

The ion exchange capacity (IEC) of the resulting CEMs could precisely be controlled by varying the molar ratio of sulfonated monomers in the reactants.

How can a polymer facilitate the conduction of anion exchange membranes?

Polymer architecture and representative chemistry schemes of anion exchange membranes. In order to enhance the mobility of side chains to facilitate the conduction of anions, our group initially synthesized AEMs with “free shuttling” side chains via the host-guest recognition of crown ether and secondary amines (Fig. 6) .
