内容記述 |
To combat global water scarcity, a novel atmospheric water harvesting (AWH) system is proposed that integrates deliquescent salts, a semipermeable membrane, and thermoresponsive hydrogels. Moisture is first absorbed by salts like CaCl2, then purified through a membrane using poly(N-isopropylacrylamide) (PNIPAm)-based hydrogels. Various PNIPAm hydrogels were developed with differing crosslinking densities, ionic charges, and hydrophilicities, including semi-interpenetrating polymer networks (semi-IPNs) containing PEG, amylopectin, or sepiolite. Water flux (W.F.) was assessed under different salt concentrations to evaluate the effects of hydrogel structure. Semi-PEG11000 and semi-IPNs with 20% amylopectin achieved high W.F. values (9.8 ± 1.0 and 19.0 ± 0.3 mL/m2h−1), indicating that large mole numbers and branched structures promote osmotic-driven water transport. Freeze-dried chitosan cryogels showed the highest W.F. (52.9 ± 10.6 mL/m2h−1), nearly five times greater than traditional semi-IPNs, highlighting the benefit of porous macrostructures. A positive correlation between storage modulus and W.F. was observed; however, molecular features also influenced performance. These results emphasize the need to optimize both mechanical and molecular properties of hydrogels. Future development will aim to enhance thermo-responsivity and water recovery efficiency, advancing practical AWH applications for atmospheric desalination. |
