Modulating hydration states of polymer micropores for ion-selective transport

Abstract

Precise ion-selective transport through membranes plays pivotal roles in electrochemical processes. Recently, in Nature, Song and coworkers reported the fine-tuning of pore hydration states by designing hydrophobic pendant groups in functional polymer membranes. Consequently, interconnecting pore networks with narrow gate sizes and optimal chemical environments were constructed in polymer membranes, resulting in superior performance in electrochemical devices.
