A Molecularly Engineered Zwitterionic Hydrogel with Strengthened Anti‐Polyelectrolyte Effect: from High‐Rate Solar Desalination to Efficient Electricity Generation (Adv. Funct. Mater. 43/2023)

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.
