Hydrophilic Wicking‐Induced Cyclic Flow for Highly Efficient and Salt‐Resistant Interfacial Solar Vapor Generator

ABSTRACT Interfacial solar vapor generation (ISVG) is a promising technology for sustainable water desalination and purification, yet its practical application is severely impeded by limited evaporation rates and salt accumulation. In this study, we introduce a pioneering synergistic water circulation management strategy based on the hydrophilic wicking effect. By synergistically integrating a 3D origami evaporator with a lateral woven fabric, we construct an efficient brine self‐circulation system. This system combines the hydrophilic wicking effect with a hierarchical porous structure to achieve self‐sustaining circulation of brine, enabling the evaporator to exhibit excellent salt tolerance and maintain stable operation even under high salinity conditions. More importantly, the designed woven fabric also serves as an environmental energy harvester, boosting the system's total energy input by 410%, significantly improving overall evaporation performance (4.63 kg m −2 h −1 ). This multifunctional, synergistic design provides a new paradigm for the efficient evaporation of high‐salinity brine. Finally, we propose a scalable industrial solution, providing important theoretical and practical insights for developing low‐cost, high‐performance, and salt‐resistant interfacial seawater desalination technologies.
