Herein, a superhydrophobic surface with superior durability was fabricated on a glass-ceramic surface by crystallization, hydrofluoric acid (HF) etching, and surface grafting. The as-prepared glass-ceramic surface was composed of three-dimensional flower-like micro-clusters, which were self-assembled from numerous nanosheets. Such a dual-scale rough surface exhibited superhydrophobicity, with a water contact angle (WCA) of 170.3° ± 0.1° and a sliding angle (SA) of ~2° after grafting with 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (FAS-17). This can be attributed to the synergistic effect between the dual-scale structure and surface chemistry. Furthermore, this surface exhibited excellent self-cleaning properties, stability against strong acid and strong alkali corrosion, and anti-stripping properties.

在此，通过结晶、氢氟酸（HF）蚀刻和表面接枝在玻璃陶瓷表面制备了具有优异耐久性的超疏水表面。所制备的玻璃陶瓷表面由三维花状微簇组成，这些微簇由大量纳米片自组装而成。这种双尺度粗糙表面表现出超疏水性，在用1H，1H，2H，2H-全氟癸基三乙氧基硅烷（FAS-17）接枝后，水接触角（WCA）为170.3°±0.1°，滑动角（SA）约为2°。这可归因于双尺度结构与表面化学之间的协同效应。此外，该表面表现出优异的自清洁性能、耐强酸强碱腐蚀稳定性和抗剥离性能。
