摘要

    摘要
  • 摘要: 将氧化石墨烯(GO)均匀分散于聚乙烯醇(PVA)水溶液中，烘干制备出表面平整的GO/PVA膜。利用激光刻蚀工艺对GO/PVA膜的表面进行处理得到LT-GO/PVA膜，研究LT-GO/PVA膜的微观结构、物理性能及其作为光热转化器件的性能。结果表明：LT-GO/PVA膜表面形成了3D多孔阵列结构，可促进太阳光的吸收，减少漫反射造成的能量损耗；LT-GO/PVA膜表面开始从亲水性向疏水性转变，可促进水的快速蒸发与分离，在1 kW/m2的光强度下，其光热水蒸发速率为1.827 kg/(m2·h)，光热转化效率为89.4%。
    Abstract: The graphene oxide (GO) was uniformly dispersed in a polyvinyl alcohol (PVA) aqueous solution, and dried to prepare a GO/PVA film with a smooth surface. The surface of GO/PVA film was treated by laser etching process to obtain LT-GO/PVA film, and the microstructure, physical properties of LT-GO/PVA film and its performance as a solar-thermal conversion device were investigated. The results show that the surface of LT-GO/PVA film forms a 3D porous array structure, which can promote the absorption of sunlight and reduce the energy loss caused by diffuse reflection. The surface of LT-GO/PVA film starts to change from hydrophilic to hydrophobic, which can enhance the evaporation and separation of water from LT-GO/PVA film surface. Under the light intensity of 1 kW/m2, the evaporation rate of water is 1.827 kg/(m2·h), and the light-to-heat conversion efficiency is 89.4%.
