It is still a significant challenge to rationally design and delicately process or fabricate anion exchange membranes (AEMs) with high ionic conductivity, good mechanical properties, and sufficient alkaline stability. Here, a polyketone (PK) resinbased AEM was synthesized via the Paal−Knorr reaction and quaternary ammonium reaction, and then processed by electrospinning and hot pressing technologies. In contrast to a quaternized functional polyketone-based polyelectrolyte (QAFPK) fabricated by casting, the electrospun QAFPK shows higher hydroxide conductivity and robust mechanical properties. QAFPK-1-6-E realizes a hydroxide conductivity of 181 mS/cm at 80 °C and a tensile strength of 54 MPa. The microphase structure characterization indicates that the electrospinning process can induce the formation of an excellent ion-conducting structure. The electrospun PKbased AEM displays great application potential in a variety of electrochemical devices under alkaline conditions, such as alkaline anion exchange membrane fuel cells (AAEMFCs).

“…Otherwise, the excellent compatibility of SU6@PPNF and SPEEK can build continuous -SO3H condensation layer at the interface between them. [10][11][12] To prove the effect of -SO3H condensation layer on conductivity, SU6-PPNF-SPEEK was prepared by incorporating the same proportion of SU6 and PPNF into SPEEK, simultaneously. The conductivity and water absorption of the SU6-PPNF-SPEEK were significantly lower than that of SU6@PPNF-SPEEK although they have similar components (Fig.…”

In this work, we fabricated cross-linked pre-oxidized polyacrylonitrile nanofibers (PPNF) coating SO3H-UiO-66 coated (named SU6@PPNF), which was introduced into sulfonated poly (ether ether ketone) SPEEK to produce membrane with superior proton conductivity, dimensional stability and mechanical properties under hydrated condition. The membrane displays a maximum power density of 172.1 mW cm-2 under 100% RH and 60 °C, which is an increase of 12.2% compared with primary membrane.
