Anti-adhesion surfaces capable of repelling various liquids would have broad technological implications. However, the on-site application of such surfaces has been limited by the need for complex processes and extra equipment. Here we have created a solvent-free mixture containing miscible silicon precursors, which can be readily sprayed, dipped, or painted onto virtually any substrate to prepare flat anti-adhesion coatings. By embedding the lubricating silicon segments on surfaces via the novel synergetic reactions that spontaneously occur at room temperature, we can fabricate coatings that are readily applicable on-site to cover large objects, and which offer excellent repellency against various liquids (water, hydrocarbons, crude oil, and oily-ink) as well as viscoelastic and sticky adhesives. These coatings are transparent, flexible, and durable. We believe these coatings can be utilized in many commercial and residential situations to address a wide range of undesirable interfacial adhesion issues such as smudge, drag, and blockage.

Superamphiphobic surfaces with extreme repellency toward both water and oily liquids have been developed from various nanocomposites with fluorinated compounds. However, the inherent rigidity and low-surface-energy of these composites restrict their adhesion and practical application in adjusting the surface wettabilities of materials. Here we report a strategy to create hybrid superamphiphobic coating with rapid contact adhesion to various kinds of substrates, strong and controllable adhesive strength, unprecedented capability of mechanical deformations, facile removal, repeatable adhesion, and simple recyclization. Our approach, inspired by snail's ideal combination of hard shell and soft epiphragm, is versatile and industrially-viable because we use the hydrogel primer to bond the fluorinated nanoparticle finish and substrates. Considering the unique characteristics of these coatings as well as the wide range of available hydrogels and nanomaterials that can be used via this approach, we envision that this snail-inspired strategy will facilitate the development and large-scale production of superamphiphobic coatings.
