Superhydrated Zwitterionic Hydrogel with Dedicated Water Channels Enables Nonfouling Solar Desalination (IMAGE)
Caption
- A superhydrated zwitterionic poly(trimethylamine N-oxide, PTMAO)/polyacrylamide/polypyrrole hydrogel (PTAP) with dedicated water channels is proposed for nonfouling solar desalination.
- The directly linked N⁺ and O⁻ groups in PTMAO establish a robust hydration shell that facilitates rapid water transport while resisting salt and microbial adhesion.
- PTAP achieves a high evaporation rate of 2.35 kg m−2 h−1 under 1 kW m–2 in 10 wt% NaCl solution for 100 h without salt accumulation, and can resists various foulants including proteins, bacterial, and algal adhesion.
