Inspired by Tillandsia leaves, an unidirectional hydrophobic membrane characterized by a hydrophilic rough surface and nm-sized hydrophobic internal pore channels is successfully synthesized. The low-frictional resistance within the synthesized asymmetric COF membrane′s pore channels is quantified using low-field NMR. Ultimately, the resulting COF membranes efficiently capture fog from the air while simultaneously filtering small molecular pollutants.
