“…To achieve high performance of AEMs, different membrane structures have been designed in the literature via strategies such as cross-linking, , branching, , blending, and block copolymerization. − Meanwhile, the introduction of a bulky, rigid unit can provide free volume to help build ion transport channels in an AEM . In our previous work, we designed an AEM incorporating polymer of intrinsic microporosity (PIM), which showed a higher conductivity (20.7 mS/cm, 25 °C) than that without PIM (15.8 mS/cm, 25 °C) at a lower IEC (0.91 vs 1.13 mmol/g) .…”
