Abstract
The harsh working environment affects the performance and usage life of Al and its alloys, thus limiting their application. In recent years, Slippery Liquid-infused Porous Surface (SLIPS) has attracted much attention due to excellent anti-corrosion, anti-fouling and anti-icing properties. This may be an effective way to improve the properties of Al and its alloys. Here, the SLIPS with petal-like structure was constructed on the Al alloy via simple hydrothermal reaction, Stearic Acid (STA) modification and lubricant injection. A variety of droplets (including oil-in-water emulsions) can slide on the SLIPS at a low angle, even the Sliding Angle (SA) of the water droplet is only 3°. Furthermore, the SLIPS exhibits outstanding mechanical and chemical properties. It can maintain fine oil-locking ability under high shearing force and keep slippery stability after immersion in acid/alkaline solutions. In addition, the SLIPS possesses excellent anti-corrosion, anti-fouling and anti-icing properties, which provides a new way to promote the application of Al and its alloys. Therefore, the SLIPS is expected to be an effective way to improve the properties of Al and its alloys, as well as play a role in anti-fouling and self-cleaning in construction, shipbuilding and automotive manufacturing industries, thereby expanding the practical application of Al and its alloys.
Highlights
As one of the commonly used engineering materials, Al and its alloys have excellent physical and mechanical properties, making Al and its alloys widely used, especially in School of Engineering and Technology, China University of Geosciences, Beijing 100083, ChinaMinistry of Education Key Laboratory for the Green Preparation and Application of Functional Materials, Hubei University, Wuhan 430062, ChinaState Key Laboratory of Solid Lubrication, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000, ChinaZhengzhou Institute, China University of Geosciences (Beijing), Zhengzhou 451283, China aerospace, automotive, machinery manufacturing, shipbuilding and chemical industry
The multi-functional Slippery Liquid-infused Porous Surface (SLIPS) have been constructed on Al alloy by a simple hydrothermal method, stearic acid modification and dimethyl silicone oil lubrication, successively
The SLIPS based on Al alloy revealed significant hydrophobicity, and has low slip angle, on which water droplets can slide at 5°
Summary
To improve the usage life of Al and its alloys and expand its application range, it should be put on agenda that improving the properties of Al and its alloys under extreme environments [1,2,3,4,5]. In recent years, it has been considered as a new and effective way to construct Superhydrophobic Surfaces (SHSs) on Al and its alloys for prevent corrosion [6, 7]. The effect of building superhydrophobic surface on Al and its alloys to improve their performance is very limited
