A novel anion exchange membrane was synthesized via crosslinking of the quaternized polyepichlorohydrin (QPECH) by 1-(3-aminopropyl) imidazole grafted poly(arylene ether ketone) (PAEK-API).While the QPECH provided an excellent ion conductive property, therigidrod-structured PAEK-API played a reinforcing role, along with providing the high conductivity associated with the pendant API group. The chem. structure of QPECH/PAEK-API membranes was identified by 1H nuclear magnetic resonace spectroscopy. A variety of membrane properties, such as anion conductivity, water uptake, length swelling percentage, and thermal, mech. and chem. stability, were investigated. The QPECH/PAEK-API1 membrane showed quite high hydroxide ion conductivity, from 0.022 S cm-1 (30°C) to 0.033 S cm-1 (80°C), and excellent mech. strength, associated with the low water uptake of less than 40%, even at 80°C. Such high conductivity at relatively low water uptake is attributed to the concentrated cationic groups, in a cross-linked structure, facilitating feasible ion transport. Further, the QPECH/PAEK-API membranes showed thermal stability up to 250°C, and chem. stability for 30 days in a 4 NaOH solution, without significant loss of ion exchange capacity. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Recommanded Product: 5036-48-6
