Abstract

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.
