The introduction of hydrophobic side chain structures in anion exchange membranes (AEMs) to facilitate ion transport has been widely studied; however, low or moderate hydrocarbon and semifluorinated chains are insufficient induce a high degree microphase separation. Herein, we design prepare poly(aryl piperidinium) AEMs with completely methylene-free perfluorinated chains, which can maximize the thermodynamic incompatibility between main- thus enhancing separation at medium capacities (IECs). According molecular dynamics study, leads better hydration cations. hydroxide conductivity chain-grafted PAP-pF-1 membrane reaches 124.9 mS cm-1 80 °C, PAP-sF-1 PAP-CH-1 show lower (116.8 104.0 cm-1). H2/O2 fuel cell using demonstrates remarkable peak power density (1651 mW cm-2 °C) durability (greater than 300 h). This work provides novel insight into AEMs; it opens up new possibilities for developing high-performance AEMs.

Microstructural Tuning of High‐Performance Bacterial Cellulose Anion Exchange Membranes via Constrained In Situ Polymerization and Double Chemical Cross‐Linking

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 2, 2024

Abstract High electrochemical and durability anion exchange membranes (AEMs) are a vital material for Flexible zinc‐air batteries (F‐ZAB) AEM water electrolysis (AEMWE) to achieve green economy environmental protection. However, the existing AEMs possess disadvantages of complicated preparation process, poor homogeneity, unsatisfactory performance. Here, novel alkaline membrane is synthesized using bacterial cellulose (BC) as matrix, incorporating constrained in situ Poly (diallyldimethylammonium chloride) (PDDA) polymerization double chemical cross‐linking techniques. By adjusting microstructure, unique long‐range order dense internal structure address issue loose bonding between PDDA BC established purpose rapid OH − conduction. The exhibit excellent application properties, with ionic conductivity (145.12 mS cm −1 ) superb mechanical strength (73.26 MPa). Consequently, assembled into F‐ZAB, unprecedented power density 258.7 mW −2 can be achieved at room temperature. Moreover, also reach 3.0 A 2.3 V, indicating good prospects field 6 m KOH. approach paves new path manufacturing energy applications.
