Robust superhydrophobic surfaces

For a superhydrophobic coating, its limited durability has been a persistent issue that prevents its usage in real-world applications. We investigate inorganic/organic hybrid coating that harnesses synergetic benefits from hydrocarbon adsorption of rare earth oxides and hydrocarbon supply from polymer. We demonstrate robust superhydrophobic coating that substantially outperforms other synthetic surfaces in terms of self-recovery of superhydrophobicity and weather resistance. Furthermore, the coating exhibits excellent weather resistance by sustaining superhydrophobicity for >1 year in the outdoor test as well as accelerated harsh weathering test.
