摘　　要：The interfacial solar evaporator is a key technology for eco-friendly desalination,playing a crucial role in alleviating the global water scarcity crisis.However,limitation of photothermal water evaporation efficiency persists due to inadequate water transfer at the water-steam interface.Herein,we present a new type of scalable and recyclable arch bridge photothermal fabric with efficient warp-direction water paths by a convenient shuttle-flying weaving technique.Compared to the previous overall layer-by-layer assembled fabric,our photothermal fabric precisely constructed effective water paths and achieved excellent water-heat distribution at the solar evaporation interface,which greatly improved the photothermal conversion efficiency and evaporation rate.By the design of the weaving process,the photothermal fabric shows a new interface contact mode of the water path fiber and polyaniline photothermal fiber.Besides,the arch-bridge type design not only minimizes heat loss area but also enhances the water evaporation area,resulting in high-efficiency all-weather available solar water evaporation.Furthermore,the results show that the temperature,evaporation rate and solar-vapor conversion efficiency of photothermal fabric can reach above 123℃,2.31 kg m^(-2)h^(-1)and 99.93%under a solar illumination of 1 kW m^(-2).The arch-bridge photo-thermal fabric with an excellent water evaporation rate has been successfully established,which provides a new paradigm for improving the sustainable seawater desalination rate.
