Abstract
Zwitterionic Hydrogels In article number 2303272, Si Yu Zheng, Jimin Fu, Jintao Yang, and co-workers design a polyzwitterionic hydrogel evaporator with an ultra-strong anti-polyelectrolyte effect, which exhibits high water uptake and low evaporation enthalpy in saline environments. Gradient-distributed polypyrrole is penetrated to realize solar-to-thermal transition and heat confinement. These advantages contribute to the boosted seawater evaporation and co-generation of freshwater and electricity.
