Angew university of Texas: Polyamphoteric ionic hydrogels for efficient atmospheric water collection

Atmospheric catchment (AWH) is considered one of the promising freshwater production strategies to provide sustainable water resources for inland and arid regions.Hygroscopic materials have attracted much attention because of their water collecting properties.However, in practice, the introduction of large amounts of inorganic salts often leads to aggregation and leakage problems.Recently, polyamphoteric ionic hydrogels have been…
