However, these two meritsappear mutually exclusive in conventional designs because of their conflictingstructural demands: Static liquid repellency necessitates minimal solid–liquidcontact, which in turn inevitably undercuts the surface’s ability to resist liquidinvasion exerted by the elevated pressure. Here, inspired by the Springtail,these two merits can be simultaneously realized by structuring surfaces attwo size scales, with a micrometric reentrant structure providing static liquidrepellency and a nanometric reentrant structure providing pressureresistance, which dexterously avoids the dilemma of their structural conflicts.The nanometric reentrants are densely packed on the micrometric ones,serving as “armor” that prevents liquids invasion by generating multilevelenergy barriers, thus naming the surface as the armored reentrants (AR)surface. The AR surface could repel liquids with very low surface tensions,such as silicone oil (21 mN m~(−1)), and simultaneously resist great pressurefrom the liquids, exemplified by enduring the impact of low-surface-tensionliquids under a high weber number (>400), the highest-pressure resistanceever reported. With its scalable fabrication and enhanced performance, ourdesign could extend the application scope of liquid-repellent surfaces towardultimate industrial settings. 收起
