"inspired by ClC-ec1 antiporter in Escherichia coli, facilitating chloride (Cl-) and proton movement... COFs integrated with aramid nanofiber membrane composite forms hydrogen-bonding network featuring amide groups selectively binding to Cl- ions, lowering energy barrier for proton conduction... in acidic environments, adding 0.1% Cl- ions (relative to protons) increases membrane's proton permeation rate 3X, reaching 9.8 mol m-2 h-1... Cl- binding stretches ANF chains, improves hydrogen-bond networks"
