Microheterogeneity of anion exchange membranes

Journal of Applied Polymer Science, 1975
Anion exchange membranes (ferricyanide ion type) prepared by the “paste method” were treated with an aqueous solution of hydrogen peroxide, and the resultant microporous membranes had no ion exchange capacity but water permeability. By measuring the water permeability of the membranes and observing the electron microphotographs of the membrane surfaces,

Poly (isatin biphenylene) polymer containing ferrocenium derivatives for anion exchange membrane fuel cell

Journal of Membrane Science, 2022
The main obstacle of anion exchange membrane fuel cell is the unsatisfactory performance of its key component anion exchange membrane. The AEMs functionalized with organometallic cations have excellent stability and comprehensive performance.

Permselectivity and microstructure of anion exchange membranes

Journal of Colloid and Interface Science, 2008
The water content, the ion exchange capacity, the transport number of counter-ion of the AMV and AMX anion exchange membranes were determined. The two-phase model (gel phase and interstitial phase) of structure microheterogeneity was validated by means of conductivity measurements.

High-Temperature Anion-Exchange Membrane Fuel Cells

ECS Meeting Abstracts
In the past few years of intensive research on Anion-Exchange Membrane (AEM) Fuel Cells (AEMFCs), amazing progress has been reported. Novel highly stable functional groups for AEMs1-4 and PGM-free catalysts5-7 were developed, new AEMFCs based on CRM-free

3D Printing of Micropatterned Anion Exchange Membranes

ACS Applied Materials & Interfaces, 2016
Micropatterned anion exchange membranes (AEMs) have been 3D printed via a photoinitiated free radical polymerization and quaternization process. The photocurable formulation, consisting of diurethane dimethacrylate (DUDA), poly(ethylene glycol) diacrylate (PEGDA), dipentaerythritol penta-/hexa- acrylate, and 4-vinylbenzyl chloride (VBC), was directly ...

Hydroxide Solvation and Transport in Anion Exchange Membranes

Journal of the American Chemical Society, 2016
Understanding hydroxide solvation and transport in anion exchange membranes (AEMs) can provide important insight into the design principles of these new membranes. To accurately model hydroxide solvation and transport, we developed a new multiscale reactive molecular dynamics model for hydroxide in aqueous solution, which was then subsequently modified

(Invited) Anion Exchange Membranes

ECS Meeting Abstracts, 2019
I didn't think I was going to work on anion exchange membranes until Shimshon gave me a call in early 2008 wanting to talk about quaternary ammonium-containing polymers. It has been an interesting journey since then. CellEra's support allowed me to hire my first postdoc - Jingling Yan - and also introduced me to a great cast of characters including ...

Metal-Cation-Based Anion Exchange Membranes

Journal of the American Chemical Society, 2012
Here we present the first metal-cation-based anion exchange membranes (AEMs), which were synthesized by copolymerization and cross-linking of a norbornene monomer functionalized with a water-soluble bis(terpyridine)ruthenium(II) complex and dicyclopentadiene. Each ruthenium complex has two associated counteranions, unlike most ammonium- and phosphonium-

On the structure–properties relationship of the AMV anion exchange membrane

Journal of Membrane Science, 2009
Important parameters such as ion exchange capacity, conductivity, permselectivity, quantity of sorbed electrolyte and water uptake of the Selemion AMV anion exchange membrane conditioned in KCl and NaCl solutions were determined in order to assess the applicability of the two-phase model of structure microheterogeneity to this case.
