Drainage-induced arch hydrogel-based interfacial evaporator drives long-term stable solar evaporation

This work introduces a double-layer arch drainage-induced hydrogel evaporator , which realizes efficient and long-term stable evaporation. Hydrogel has developed into a very important platform in solar interface evaporator. However, the current hydrogel evaporators are usually three-dimensional evaporators, which will consume a lot of raw materials. Thus, a new two-dimensional hydrogel evaporator is urgently needed to alleviate this problem. Here, a double layer hydrogel evaporator was designed by twice vacuum filtration. Furthermore, through the arched design and the introduction of concentrated brine drainage system, the hydrogel evaporator has enhanced water transportation and tailored water transportation…
