Biomimetic-Inspired Cross-Scale Hydrogel Evaporator with Synergetic Light-Heat-Water-Salt Management for Highly-Efficient and Stable Brine Evaporation

Hydrogel-based solar-driven interfacial vapor generation is considered an effective method for freshwater production. However, traditional hydrogel evaporators suffer from weak mechanical strength and the trade-off between high evaporation rates and...
