Solar-driven photothermal water evaporation is considered an elegant and sustainable technology for freshwater production. The existing systems, however, often suffer from poor stability biofouling issues, which severely hamper their prospects in practical applications. Conventionally, materials are deposited on the membrane supports via vacuum-assisted filtration or dip-coating methods. Nevertheless, weak inherent material-membrane interactions frequently lead to durability, material layer...
