Selective ion transport through hydrated micropores in polymer membranes.

ABSTRACT: Ion-conducting polymer membranes are essential in many separation processes and electrochemical devices, including electrodialysis¹, redox flow batteries², fuel cells³ and electrolysers^4,5. Controlling ion transport and selectivity in these membranes largely hinges on the manipulation of pore size. Although membrane pore structures can be designed in the dry state⁶, they are redefined upon hydration owing to swelling in electrolyte solutions. Strategies to control pore hydration and a deeper understanding of pore structure evolution are vital for accurate pore size tuning. Here we report polymer membranes containing pendant groups of varying hydrophobicity, strategically positioned near charged groups to regulate their hydration capaci
