Bioinspired Hollow Fibers With Efficient Transport Channels for Wide Humidity Atmospheric Water Harvesting
Tianjin University of Science and Technology
Abstract
ABSTRACT To address global freshwater scarcity, atmospheric water harvesting (AWH) offers a sustainable solution by extracting moisture from air. However, existing AWH materials struggle to combine high water uptake across a wide humidity range with portability. To resolve this limitation, a cotton‐like hollow fiber with low moisture vapor transmission resistance and fast adsorption kinetics is fabricated by coaxial wet‐spinning. The hybrid fiber employs sulfonated cellulose nanofiber (s‐CNF) and sodium alginate (SA) as hydrophilic network to provide effective moisture retention, and used carbon nanotube (CNT) for photothermal water evaporation. The hollow architecture provides additional sites for LiCl…
