目的 解决传统的全氟聚醚疏油防指纹涂层对提高触摸屏防指纹效果不明显的问题。方法 基于对蝉翼表面纳米阵列微观结构形貌的表征,通过金快速热退火模板法和反应离子刻蚀技术,制备了仿蝉翼超疏水疏油防指纹表面。基于指纹图像阈值算法和表面粗糙度因子模拟计算,评价分析了其防指纹特性。结果 仿蝉翼超疏水表面水接触角为(152±1)°,指纹油接触角为(118±2)°,十六烷接触角为(111±2)°,表面透光率为95.6%,展现出卓越的超疏水疏油特性和光学特性。同时,仿蝉翼超疏水疏油表面的抗指纹性相对于全氟聚醚改性平玻璃疏油表面提升了28.3%以上,表现出良好的防指纹特性。此外,按压指纹后的仿蝉翼超疏水疏油表面经过1次标准无纺布擦拭实验后,表面指纹率相对于擦拭前降低了40%,指纹降低率远高于改性平玻璃疏油表面,说明了其优异的指纹易擦洗特性。另外,经过20 min落砂实验后,仿蝉翼超疏水疏油表面仍然可以保持良好的抗指纹特性,说明其具有良好的耐机械磨损特性。结论 仿蝉翼超疏水疏油表面具有优异的超疏水疏油特性和光学特性,同时,表面致密的纳米阵列赋予了其良好的抗指纹特性。经测试发现,该表面具有优异的指纹易擦洗特性和机械耐久性,为未来防指纹玻璃的设计提供了新的思路。 |

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. |
