摘　　要：工业制造及石油泄漏产生的含油废水含量越发增加,导致水体受污染程度越发严峻。具有特殊润湿性的界面材料成为处理含油废水的首选材料,但是对于高黏度油而言,具有光热性能的超疏水材料可对其进行处理。因此,基于光热转换的超疏水材料用于原油吸附和油水分离领域成为研究热点。本文先介绍了光热超疏水材料的润湿性原理及光热转换机理,然后综述了其用于油水分离和原油吸附的最新研究进展,最后提出了光热超疏水材料在油水分离和原油吸附领域的不足之处并展望了其后续发展进程和工业应用前景。Increasing levels of oily wastewater from industrial manufacturing and oil spills, leading to more and more serious levels of contamination of water bodies. Interfacial materials with special wettability have become the materials of choice for treating oily wastewater, but for highly viscous oils, superhydrophobic materials with photothermal properties can treat them. Therefore, superhydrophobic materials based on photothermal conversion for crude oil adsorption and oil/ water separation have become a research hotspot. In this paper, we first introduce the wettability principle of photothermal superhydrophobic materials and the mechanism of photothermal conversion, then summarized the recent research progress on its use for oil/water separation and crude oil adsorption, finally, the shortcomings of photothermal superhydrophobic materials in the field of oil/water separation and crude oil adsorption are proposed and their subsequent development process and industrial application prospects are anticipated.
