Highly conductive partially cross-linked poly(2,6-dimethyl-1,4-phenylene oxide) as anion exchange membrane and ionomer for water electrolysis

Fabrication of Dual-Functional Bacterial-Cellulose-Based Composite Anion Exchange Membranes with High Dimensional Stability and Ionic Conductivity

“…It was also accompanied by enhancement of the CH 2 stretching vibrational peaks at 2916 and 2846 cm −1 and the C�C bending vibrational peak for the PPO arene ring at 1660 cm −1 . 32 This is also shown in Figure 3c and was more pronounced in PBC 3 /QPPO. Additionally, Figure S3 displays the XPS full-spectrum and high-resolution N 1s XPS spectra of PBC 3 and PBC 3 /QPPO.…”

Key components and design strategy of the membrane electrode assembly for alkaline water electrolysis

“…Representative ether-containing AEMs for water electrolysis include those prepared from poly(arylene ether ketone) with an imidazolium functional group 256 and a cyclic ammonium functional group, 204 quaternary ammonium polysulfone, 18,180,229 and poly(2, 6-dimethyl-1,4-phenylene oxide) with aliphatic cationic side chains. 213,227,233,257 These AEMs have moderately low hydroxide conductivities of 20-50 mS cm À1 and current densities of 200-500 mA cm À2 at 1.8 V cell for water electrolysis (Fig. 14c).…”

Recent progress in anion exchange membranes (AEMs) in water electrolysis: synthesis, physio-chemical analysis, properties, and applications

“…27,29,32,45,49,50,55,57,58,[150][151][152][153][154][155][156][157][158][159][160][161][162] In addition, there are reviews on AEMs such as molecular design and microscopy analysis of membranes for fuel cell and water electrolysis, dealing with alkaline durability of imidazoliumbased AEMs, synthesis of ion-exchange membranes for various applications, synthetic approaches for alkaline-stable AEMs, Friedel-Cras reaction-based synthesis of AEMs for fuel cell and electrolysis applications, click chemistry in AEMs for energy-based applications, the signicance of polymer ion exchange membrane structures and properties for hydrogen production by water electrolysis, synthesis of silica-AEMs composite, and anion exchange polyelectrolytes for the synthesis of AEMs and ionomers. 50,88,145,160,[163][164][165][166][167][168][169][170][171][172][173] However, no comprehensive review of AEMs from synthesis to application through physiochemical analysis and evaluation of properties has been identied in recent studies. This review is distinct from other contemporary works because it thoroughly reviews the synthesis of AEMs, such as hydrocarbon and uorine, with choices of homogeneous (organic/organic) and heterogeneous…”
