Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane
ABSTRACT Sorption‐based atmospheric water harvesting (SAWH) offers a promising route for decentralized freshwater production, but practical water output is often limited by slow sorption kinetics in salt‐loaded hydrogel sorbents. Here, a biomimetic multi‐layer heterogeneous hygroscopic (MHH) membrane is developed to de...
