Ionization Engineering of Hydrogels Enables Highly Efficient Salt-Impeded Solar Evaporation and Night-Time Electricity Harvesting
Abstract
Highlights An ionization-engineered hydrogel with electronegativity polymer chains to impede salt ions was designed. The hydrogel evaporator exhibited salt impedance in 20 wt% brine for 15 days with a high evaporation efficiency of 95.6%. An all-day high-salinity brine treatment with zero liquid discharge was proposed.
