各种表面改性技术已被用来开发超疏水表面，但其耐久性已被公认为是真实的应用的主要障碍。在这里进行了定量研究，以评估不同的表面改性方法对表面的机械耐久性的影响。采用硅溶胶（SS）、十八烷酸（OA）、十七碳-1，1，2，2-四氢癸基三氯硅烷（HDFS）和十六烷基三乙氧基硅烷（HTS）4种低表面能材料，通过化学修饰和刻蚀、喷砂两种表面粗糙化方法相结合制备了超疏水表面。利用XPS分析了表面的元素组成，利用AFM测量了表面的粗糙度。这些表面的耐久性通过砂纸磨损实验来测试。结果表明，低表面能材料对表面粗糙度有显著的影响，这将对这些粗糙表面的耐久性起重要作用。与其他三种低表面能材料相比，SS改性的粗糙表面具有更高的粗糙度和更好的耐久性。在1500 CW砂纸上，用10 g重的重锤，SS改性粗糙表面可以承受60次磨损循环。
Various surface modification technologies have been used to develop superhydrophobic surface, however their durability has been recognized as the major obstacle for the real applications. Here a quantitative investigation was conducted to evaluate the effects of different surface modification methods on the surfaces’ mechanical durability. The superhydrophobic surfaces were prepared by the combination of two surface roughing methods (etching and sandblasting) with chemical modifications with four low surface energy materials: silica sol (SS), octadecanoic acid (OA), heptadecafluoro-1,1,2,2-tetrahydrodecyltrichlorosilane (HDFS) and hexadecyltriethoxysilane (HTS). XPS was used to analyze the elements composition and AFM was used to measure the roughness of the surfaces. The durability of these surfaces was tested by a sandpaper abrasion experiment. The collective results showed that the low surface energy materials had significant effects on the surface roughness, which would then play an important role in the durability of these rough surfaces. The SS modified rough surfaces possessed higher roughness and better durability than the surfaces modified by other three low surface energy materials. SS modified rough surfaces could bear 60 cycles of abrasion with 10 g weights on 1500 CW sandpaper.
