| 英文摘要 | Hot water droplet and oils induced air cushion failure, intensively used fluorine-containing chemicals,tedious preparation process, etc. are the main bottlenecks of the current artificially fabricated superhydrophobic materials, restricting their large-scale production and real-world applications. Herein, a facile,scalable, fluorine-free spray-coating strategy was employed to achieve superhydrophobic and superoleophobic polymerized organosilanes/Al_2O_3 nanoparticles(POS/Al_2O_3 NPs) coatings. The POS/Al_2O_3 NPs coating was achieved through hydrolytic condensation of tetraethyl orthoilicate(TEOS) and hexadecyltrimethoxysilane(HDTMS) in the presence of Al_2O_3 NPs. A variety of analytical techniques including scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), energy dispersive X-ray photoelectron spectroscopy(EDS) were used to investigate the fabricated coatings. The POS/Al_2O_3 NPs coating features high contact angle(>158°) and low sliding angle(<5°) for water, glycerol, and ethylene glycol droplets with different surface tensions, verifying both superhydrophobic and superoleophobic properties. Moreover, the coatings present extremely low surface adhesion force, excellent liquid-driven self-cleaning ability, and hot water repellency. The superamphiphobic POS/Al_2O_3 NPs coating exhibits promising applications in various fields including self-cleaning, corrosion resistance, and preventing scald as this strategy is applicable on various substrates. |
