Inspired by the lotus leaf effect, superhydrophobic coatings havesignificant potential in various fields, However, their poor pressure resistance,weak mechanical durability, and complex preparation processes severely limitpractical applications. Here, a method for preparing pressure-resistant anddurable superhydrophobic coatings by simply spray-coating a phase separationsuspension containing fluorinated silica nanoparticles and polyolefinadhesive onto substrates is introduced, which forms superhydrophobiccoatings with a porous and hierarchical micro-/nanostructure. Theresulting superhydrophobic coatings exhibit outstanding pressure resistance,maintaining a Cassie-Baxte state after 18 days of submersion in 1 m of water. Furthermore, the coatings demonstrate remarkable mechanical durability,withstanding 200 cycles of Taber abrasion, 100 cycles of tape-peeling, and750 g of sand abrasion. The coatings also show excellent chemical stability,enduring long-term immersion in corrosive liquids and 120 d of outdoorexposure. Additionally, the coatings display excellent anti-icing propertiesand can be applied to various substrate surfaces. This approach improveson the limitations of conventional superhydrophobic coatings and acceleratesthe application of superhydrophobic coatings in real-world environments.
