Abstract

Developing versatile and robust surfaces that mimic the skins of living be-ings to regulate air/liquid/solid matter is critical for many bioinspired appli-cations. Despite notable achievements, such as in the case of developing robust superhydrophobic surfaces, it remains elusive to realize simulta-neously topology-specific superwettability and multipronged durability owing to their inherent tradeoff and the lack of a scalable fabrication method. Here, we present a largely unexplored strategy of preparing an all-perfluoropolymer (Teflon), nonlinear stability-assisted monolithic sur-face for efficient regulating matters. The key to achieving topology-specific superwettability and multilevel durability is the geometric-material me-chanics design coupling superwettability stability and mechanical strength. The versatility of the surface is evidenced by its manufacturing feasibility, multiple-use modes (coating, membrane, and adhesive tape), long-term air trapping in 9-m-deep water, low-fouling droplet transportation, and self-cleaning of nanodirt. We also demonstrate its multilevel durability, including strong substrate adhesion, mechanical robustness, and chemical stability, all of which are needed for real-world applications.
