Solid-like Slippery Surface with Excellent Comprehensive Performance

Slipperysurfaces with outstanding slippery performances have shownapplication prospects in various fields, including anti-icing, antifouling,droplet transportation, and fog collection. However, practical applicationof 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-Alshows exceptional water-slippery ability with a sliding angle of 5 & DEG;and antifouling ability. Durability and chemical stability tests confirmthe high surface durability and chemical stability of SSS-Al. Furthermore,SSS-Al exhibits anti-icing performance, fog collection ability, andelectrochemical corrosion resistance, as well as demonstrates remarkableapplication prospects in important fields such as aerospace and shipbuilding.
