Surface structure is a key factor for the non‐wettability, that's because different surface tier structure can catch different numbers of air‐pockets. The weak hierarchical surface structure limits the application of non‐wetting materials. In this work, the different tier structure Te@C, Te@C‐SiO 2 , SNTs are prepared to characterize the influence of tier structure on the non‐wettability and N 2 adsorption–desorption isotherms are used to characterize the air‐pockets. The aluminum dihydrogen phosphate is used to strength the robustness of SiO 2 NTs superamphiphobic surface. The results indicate that the more tiers of surface structure have a higher S BET , higher S BET ensure enough air‐pockets, which can make more contributions to the non‐wettability. The prepared robust superamphiphobic surface shown extreme robustness, and after 50 cycles of sandpaper abrasion, it is still super‐repellent to hexadecane.
