Solar-assisted smart nanofibrous membranes for atmospheric water harvesting

• The hybrid nanofibers for sorption-based atmospheric water harvesting have been demonstrated. • The synergistic effect of hydrophilicity-switchable polymer and hygroscopic salt realizes efficient moisture capturing. • The hybrid nanofibers exhibited in situ water liquefaction, and rapid water oozing. • The nanofiber-based water harvesting system has been validated in an actual outdoor experiment. The enormous reserves of atmospheric freshwater...
