摘　　要：本研究根据太阳能驱动的界面水蒸发原理及丙纶纤维的结构和性能,仿生制备垂直排列的丙纶纤维集合体,研究其吸湿导水性能,并在其表面构筑光热转换效率较高的材料氧化石墨烯(GO),进而探索其在太阳能驱动作用下蒸发水的应用。试验结果表明,丙纶纤维基太阳能-水蒸发器蒸发效果显著,在 1 kW/m^(2)的光照条件下蒸发速率高达 1.05 kg/(m^(2)·h),蒸发效率为 75%,经过多次循环测试后,蒸发性能仍保持稳定。In this study, based on the principle of solar water-driven interface water evaporation and the structure and properties of polypropylene fibers, bionic preparation of vertically aligned polypropylene fiber aggregates was studied to study their moisture absorption and water conductivity, and graphene oxide(GO) with high light-to-heat conversion efficiency were constructed on their surfaces to explore their The application of water evaporation under the action of solar energy. The experimental results show that the polypropylene fiber-based solar-water evaporator has a significant evaporation effect. The evaporation rate is as high as 1.05 kg/(m^(2)·h) under 1 kW/m^(2) light conditions, and the evaporation efficiency is75%. After many cycles of testing, the evaporation performance remains stable.
