Abstract
AbstractPorous materials‐assisted atmospheric water harvesting (AWH) approaches are attractive for addressing the severe shortage of freshwater resources. Herein, ionothermal polymerization approach was employed to realize four porous organic polymers (FJU‐CTFs) with strong hydration stability and low skeleton density for atmospheric water harvesting. The materials exhibited ultra‐high water vapor adsorption capacity (1108 cm3 g−1), s‐type adsorption isotherms, and rapid filling of water vapor in the pores of the materials under low humidity conditions. It has the characteristics of atmospheric water harvesting from the air at lower humidity (30 %–40 %) and narrow temperature (30–35 °C). A total of 30 times of water adsorption‐desorption cycles showed the excellent working ability and hydrolytic stability of FJU‐CTFs, which provided new solutions for the application of porous materials in AWH and expanded new material types.
