We report on an electrochemically driven CO2 separation process employing commercial anion exchange membranes to directly remove from a dilute gas mixture and transport it across cell. This m...

In the pursuit of good performing, low cost, and scalable anion-exchange membranes (AEM), a series blended electrolytes based on cross-linked quaternized poly epichlorohydrin (qPECH) polyvin...

Fabricating crosslinked radiation-grafted anion-exchange membranes using a diamine in the amination synthesis step leads to better permselectivity-resistance balance compared use of divinylbenzene grafting step.

Within an electrodialysis unit, the solutions are separated by alternately arranged anion exchange membranes (permeable only for anions) and cation exchange membranes (permeable only for cations). The membranes are arranged parallel to one another to form an electrodialysis stack. When a potential is applied across the selectively permeable membrane stack, anions selectively move through the an...

Abstract The lack of anion exchange membranes (AEMs) that possess both high hydroxide conductivity and stable mechanical chemical properties poses a major challenge to the development high‐performance fuel cells. Improving one side balance between stability usually means sacrificing other. Herein, we used facile, high‐yield reactions design synthesize piperidinium polymer with polyethylene back...

In this study, commercially available cation- and anion-exchange membranes were investigated in hybrid liquid/gas electrolyzers by coupling situ ambient pressure hard X-ray photoelectron spectroscopy with finite element analysis.

Polymeric ion-exchange membranes have come a long way since their invention, benefiting wide range of processes, ranging from desalination to fuel cells. However, challenges such as alkaline stability, monovalent ion selectivity, cost-effectivity, and process sustainability largely persist. This work showcases stable anion-exchange made by hot-pressing polyelectrolyte complex poly(styrenesulfon...

Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...
