摘要

Superhydrophobic (SH) surfaces show considerable potential for fluid drag reduction, yet rapidly fabricating surfaces that combine superhydrophobicity with superaerophilicity remains challenging. Herein, we present a rapid, one-step flame pyrolysis strategy to fabricate SH coatings that exhibit static superhydrophobicity/superaerophilicity, dynamic impact resistance, and notable drag reduction performance. angle below 1.0°. Under impact at high Weber number (326.7) and Reynolds number (8400.0), the droplet enables complete bouncing within 15 ms, reflecting excellent dynamic stability. Owing to the superaerophilicity of the micro-nano composite structure and its ability to sustain a stable Cassie–Baxter state, the SH spheres exhibit a 40% increase in movement speed across water surface relative to the pristine PDMS spheres. Notably, the entire coating can be fabricated within only 3 s, demonstrating high feasibility for practical applications. These results highlight the strong potential of our flame-pyrolyzed SH coatings in fluid drag reduction.
