Hydrogel as a solar evaporator shows great potential in freshwater production. However, hydrogels often lead to an imbalance between energy input and water supply management due their excessively high saturated content. Thus, achieving stable water-energy-balance hydrogel evaporators remains challenging. Here, by tortuosity engineering designed transport channels, seamless high-tortuosity/low-tortuosity/high-tortuosity structured (SHLH structure hydrogel) is developed, which enables the with customized rate, leading controlled at interface.
