This study presents a novel scalable, and easy-to-recycle arch-bridge photothermal fabric (ABPF) solar evaporator, fabricated through a conventional weaving method utilizing flexible photothermal fibers as the weft and hydrophilic fibers as the warp.
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.
It is necessary to decide the appropriate design of water channel based on the consideration of entire evaporator design and the application mode. Because of the great restriction to contact with bulk water, water transfer in evaporation system become one of the critical influence factors on photothermal evaporation. 4.2.
