太阳能驱动界面蒸发具有蒸发速度快、光热转换效率高的特点，在海水淡化中具有广阔的应用前景。受折纸结构的多功能性和可部署性的启发，我们展示了一个基于折纸图案的便携式水弹塔状结构，命名为“折纸塔”，作为漂浮在水面上的可转换光热蒸发器，用于高效的太阳能驱动界面淡化。折纸塔具有可预测的变形能力，具有可逆的径向膨胀和径向收缩，并伴有轴向的微小变化。折纸塔的可逆可调性为运输和储存提供了便利，而快速扩展成其塔形提供了快速部署能力。得益于扩大的蒸发表面，出色的光捕获能力和热定位，折纸塔光热蒸发器在一次太阳照射下的蒸发速率为2.67 kg m−2 h−1。这种可逆的3D折纸光热蒸发器为构建便携式高效太阳能热脱盐系统开辟了新的途径。
Configured with a rapid evaporation rate and a high photothermal conversion efficiency, solar-driven interfacial evaporation displays considerable promise for seawater desalination. Inspired by the versatility and deployability of origami-based structures, we demonstrate a portable waterbomb origami pattern-based tower-like structure, named an “origami tower”, as a convertible photothermal evaporator floating on water for efficient solar-driven interfacial desalination. The origami tower has predictable deformability, featuring reversible radial expansion and contraction radially accompanied by small changes in the axial direction. The reversible adjustability of the origami tower offers convenience for transportation and storage, while the quick expansion into its tower shape provides rapid deployment capabilities. Benefiting from an enlarged evaporation surface, excellent light trapping ability, and heat localization, the origami-tower photothermal evaporator yields an evaporation rate of 2.67 kg m−2 h−1 under one sun illumination. This reversible 3D origami-based photothermal evaporator opens a new avenue for building a portable and efficient solar thermal desalination system.
