Abstract Highly porous metal-organic framework (MOF) nanosheets have shown promising potential for efficient water sorption kinetics in atmospheric harvesting (AWH) systems. However, the uptake of single-component MOF absorbents remains limited due to their low retention. To overcome this limitation, we present a strategy fabricating vertically aligned on hydrogel membrane substrates (MOF-CT/PVA) achieve ultrafast AWH with high uptake. By employing directional growth nanosheets, successfully create superhydrophilic coating layer and pore channels transportation crosslinked flexible membrane. The designed composite harvester exhibits kinetics, achieving 91.4% saturation within 15 min. Moreover, MOF-CT/PVA superior solar-driven capture-release capacity even after 10 cycles reuse. This construction approach significantly enhances vapor adsorption, offering solution design MOF-membrane harvesters mitigate freshwater crisis.
