High-performance and durable anion exchange membranes (AEMs) are critical for realizing economical green hydrogen production through alkaline water electrolysis (AWE) or AEM electrosysis (AEMWE). However, existing AEMs require sophisticated fabrication protocols exhibit unsatisfactory electrochemical performance long-term durability. Here we report an fabricated via a one-pot, in situ interfacial Menshutkin reaction, which assembles highly cross-linked polymer containing high-density quaternary ammoniums nanovoids inside reinforcing porous support. This structure endows the membrane with high anion-conducting ability, uptake (but low swelling), mechanical thermochemical robustness. Consequently, assembled achieves excellent AWE (0.97 A cm

Thermodynamics of mobile ions in swollen ion exchange membranes (IEM) are essential for understanding their permselectivity. The theoretical modeling the activity coefficient and partitioning IEM is challenging. Based on a water-swollen membrane reference state quasi-regular solution model, we successfully correlated various IEMs. For all studied 59 systems, correlation r determination R2 0.973 0.947, respectively. As expected, water between external salt represented. In new theory framework, standard chemical potential counterion different from that aqueous solution.

Limitations in existing anion exchange membranes deter their use the efficient treatment of industrial wastewater effluent. This work presents an approach to fabricating novel anion-conducting using epoxy resin monomers like hydrophobic or hydrophilic diglycidyl ether and quaternized polyethyleneimine (PEI). Manipulating nature, quantitative composition copolymer conditions quaternization allows control physicochemical properties membranes, including water uptake (20.0–330%), ion capacity (1.5–3.7 mmol/g), ionic conductivity (0.2–17 mS/cm Cl form at 20 °C), potentiostatic transport numbers (75–97%), as well mechanical properties. A relationship was established between structure conductivity/selectivity trade-off. The higher polyethyleneimine, diluent fraction, hydrophilicity ether, lower permselectivity. Hydrophobic gives a much better ratio since it provides degree hydration than ether. Different mesh non-woven reinforcing materials were also examined. developed demonstrate good stability both neutral acidic environments, benchmark characteristics laboratory electrodialysis cells batch-mode dialysis experiments are similar superior to, commercial such Neosepta© AMX, FujiFilm© Type1, Fumasep FAD-PET.
