| Abstract: |
| In terms of the limited performance of traditional perfluoropolyether-based oleophobic anti-fingerprint coatings to prevent the deposition of fingerprints on glass. Based on the characterization of the surface microstructure of cicada-wing, the biomimetic cicada-wing superhydro(oleo)phobic surface was prepared by combining gold rapid thermal annealing template method and reactive ion etching technique. Its anti-fingerprint characteristics were evaluated and analyzed according to fingerprint image threshold algorithm and surface roughness factor simulation calculation. The biomimetic cicada-wing superhydro(oleo)phobic surface exhibited excellent superhydrophobicity, oleophobicity and optical properties. The water contact angle, fingerprint oil contact angle and n-hexadecane contact angle were (152±1)°, (118±2)° and (111±2)°, respectively. Besides, the biomimetic cicada-wing super hydro(oleo)phobic surface illustrated a 28.3% increase in fingerprint resistance over conventional oleophobic glass. After a standard non-woven cloth wiping experiment, the fingerprint rate of biomimetic cicada-wing superhydro(oleo)phobic surface decreased by 40%, which was much lower than the fingerprint reduction rate of the modified flat glass surface, indicating its excellent characteristics for fingerprints to be cleaned. The superhydro(oleo)phobic surface also maintained stable anti-fingerprint properties after 20 min continuous sand impact, illustrating good mechanical robustness. Thus, the biomimetic cicada-wing superhydro(oleo)phobic surface has excellent superhydrophobic and oil-repellent properties and optical properties. Meanwhile, the dense surface nanoarray gives it good anti-fingerprint properties. It is found that the surface has excellent characteristics for fingerprints to be cleaned and mechanical durability. Therefore, our findings provide a new insight for the future design of anti-fingerprint glass. |
