Solid-like Slippery Surface with Excellent Comprehensive Performance

Slippery
surfaces with outstanding slippery performances have shown
application prospects in various fields, including anti-icing, antifouling,
droplet transportation, and fog collection. However, practical application
of the existing slippery surfaces is limited by lubricating oil loss,
low water-slippery ability, low surface robustness, complex processes,
and high costs. To overcome these limitations, we propose a facile,
low-cost method to create a solid-like slippery Al surface (SSS-Al)
by mixing hydrophobic nano-ceramic coating, silicone oil, and nano-SiO2, which shows excellent comprehensive performance. The SSS-Al
shows exceptional water-slippery ability with a sliding angle of 5°
and antifouling ability. Durability and chemical stability tests confirm
the high surface durability and chemical stability of SSS-Al. Furthermore,
SSS-Al exhibits anti-icing performance, fog collection ability, and
electrochemical corrosion resistance, as well as demonstrates remarkable
application prospects in important fields such as aerospace and shipbuilding.
