摘　　要：仿生超疏水表面在油水分离、防结冰、自清洁等方面具有广阔的应用前景。但是由于其表面结构的脆弱所造成的不稳定性,使其在应用时受到较大限制。飞秒激光作为一种通用的微纳加工方法,在超疏水表面的制备中有许多明显的优势,并且适用于几乎任何硬质材料的加工。本文从浸润性的基本模型出发,分析了耐久型超疏水表面的特点,针对耐久型超疏水表面的飞秒激光制备方法以及应用进行了概述,从聚合物、玻璃以及金属等物质的超疏水表面的飞秒激光制备进行了归纳。对超疏水表面在油水分离、防结冰、自清洁等方面的应用研究进行了综述。最后总结了利用飞秒激光制备耐久型超疏水表面所面临的挑战。Although superhydrophobic surfaces have shown great potential in oil-water separation,antiicing and self-cleaning,the practical applications were often limited by their brittle durability. The fragility of superhydrophobic surface structure is the main reason that hinders its practical application. Due to the further study of superhydrophobic surface,the failure of superhydrophobic surface has also been explored.This paper reviews the research progress of durable superhydrophobic surface prepared femtosecond laser and its application.In the section of background,firstly,several basic wettability models are introduced,and the characteristics of durable superhydrophobic surfaces are analyzed. Then,the advantages of femtosecond laser micro-nano processing in the preparation of superhydrophobic surfaces are discussed. The research progress of femtosecond laser preparation of the durable superhydrophobic surface for different materials such as polymer,metal and glass were concluded. The application fields of durable superhydrophobic surface fabricated by femtosecond laser were summarized.There are several methods to improve the durability of the superhydrophobic surface according to the application requirements. Firstly,the mechanical stability of the superhydrophobic surface with multi-scale micro-nanocomposite structure is much higher than that of the single micron or nano-scale rough structure.Secondly,the durability of superhydrophobic surface can also be improved by strengthening the surface microstructure on the material surface through the bonding layer. This form of adhesive can not only strengthen the bonding strength between microstructure and surface,but also play a buffer role when the surface is impacted by external force,protecting the micro-nano rough structure,and effectively improving the mechanical durability of superhydrophobic surface. Thirdly,the physical protection of micro-nano structures is carried out by constructing a surface protective layer,thereby improving their mechanical durability. Fin
