Crosslinked quaternary phosphonium-functionalized poly(ether ether ketone) polymer-based anion-exchange membranes

, 2021
A series of mechanically robust and highly conducting crosslinked anion-exchange membranes are synthesized by using quaternary phosphonium-functionalized poly(ether ether ketone) (QPPEEK) as base polymer and poly(ethylene glycol) (PEG) as the crosslinker.

The effect of –NH− on quaternized polybenzimidazole anion exchange membranes for alkaline fuel cells

, 2021
To investigate the effect of –NH− in polybenzimidazole (PBI) on the properties of PBI anion exchange membranes (AEMs), naphthalene based polybenzimidazole (NPBI) was partially grafted with cationic side chains to afford NPBI-QAx membrane, and then ...

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,

Development of Pore-Filling Anion Exchange Membranes for Anion Exchange Membrane Water Electrolysis: Enhancement of Resistance

ECS Meeting Abstracts, 2022
Water electrolysis is a process that uses electricity to decompose water into oxygen and hydrogen. There are several types of ion exchange membrane can be used, anion exchange membrane, proton exchange membrane and bipolar membrane for water electrolysis.

Alkaline-stable anion exchange membranes: A review of synthetic approaches

, 2020
In honor of the 100th anniversary of Staudinger’s “Polymer Hypothesis”, we write this trend review to describe some key developments in the synthesis of cationic polymers. Cationic polymers provided early evidence in support of the Polymer Hypothesis and

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.

Comparative study of anion exchange membranes for low-cost water electrolysis

International journal of hydrogen energy, 2020
Various anion-exchange membranes (AEMs) were studied in the electrolysis cell using the non-precious metal-based catalysts showing the good potential of selected AEMs in low-cost water electrolysis application. The 0.1–1 M potassium hydroxide electrolyte
