This paper presents a method for fabricating substrate-independent superhydrophobic surfaces using femtosecond laser-chemical hybrid processing. The approach involves creating micro/nanostructures on substrates via femtosecond laser direct writing technology, followed by modification with stearic acid. The resulting surfaces exhibit excellent superhydrophobic and self-cleaning properties. The surfaces remain stable under various conditions, including heating to 100°C, washing 10 times, and exposure to air for 60 days. This method is applicable to various substrates such as ceramic, titanium, silicon, and quartz glass. The superhydrophobic surfaces prepared by this method show good stability and performance. Superhydrophobic surfaces have high roughness and low surface energy, with water contact angles greater than 150° and sliding angles less than 10°. These surfaces have various applications, including self-cleaning, anti-corrosion, oil/water separation, and droplet manipulation. However, existing methods for preparing superhydrophobic surfaces are often substrate-dependent and complex. This study proposes a new method that combines femtosecond laser and chemical processing to achieve substrate-independent superhydrophobic surfaces. The method involves laser processing to create micro/nanostructures on the substrate surface, followed by coating with stearic acid to reduce surface energy and improve hydrophobicity. The resulting surfaces are stable and effective for various applications. The method is simple and efficient, making it a promising approach for fabricating superhydrophobic surfaces.This paper presents a method for fabricating substrate-independent superhydrophobic surfaces using femtosecond laser-chemical hybrid processing.
