| Abstract: |
| Wetting, the natural ability of a liquid to spread across a solid surface, is a ubiquitous and significant physicochemical phenomenon in nature, exerting profound influences across numerous fields, including industrial manufacturing, biological science physical research, aerospace engineering, and nautical technology. Superamphiphobic surfaces, as a special type of wettability surfaces, exhibit exceptionally high contact angles and extremely low rolling angles for both water and oil, demonstrating remarkable hydrophobic and oleophobic properties. Due to their outstanding performance, superamphiphobic surfaces excel in self-cleaning, corrosion resistance, antibacterial properties, anti-icing and de-icing capabilities, and resistance to biofouling. Consequently, they hold vast and potential application prospects in various domains such as daily life, industrial production, liquid transportation, aerospace, and nautical industries. The superamphiphobic characteristics of material surfaces result from the combined effects of their surface chemical composition and surface roughness structure. Based on this, the preparation of superamphiphobic surfaces usually involves two steps:the first step is to construct a rough structure on material surface, and the second step is to modify the rough surface with low surface energy substances. Researchers in the industry have developed various preparation techniques for superamphiphobic surfaces based on the above principles. However, due to the fragility of the micro-nano rough structure of the superamphiphobic surface, once the surface microstructure or chemical substances are damaged, the superamphiphobicity may be affected or even fail. Therefore, the low durability of the material surface is a technical bottleneck limiting the large-scale promotion and application of superamphiphobic surfaces. Improving the mechanical durability of superamphiphobic surfaces a key issue that needs to be urgently addressed in the industry. In recent years, many studies have been dedicated to enhancing the durability of superamphiphobic surfaces, mainly focusing on optimizing surface microstructures and improving the adhesion of low surface energy substances. This paper first summarizes the wetting theory and design basis of superamphiphobic surfaces, systematically summarizes various preparation methods including the layer-by-layer self-assembly method, the template method, the electrochemical deposition method, and the vapor deposition method, and delves into the durability characteristics of superamphiphobic surfaces obtained by the above preparation methods. Subsequently, the paper highlights the techniques and methods employed to improve the durability of superamphiphobic surfaces, elucidating the durability enhancement mechanisms, advantages, and disadvantages of each approach. The discussion covers a range of strategies, from modifying surface roughness and chemistry to incorporating robust binding agents that enhance adhesion between the low-surface-energy coating and the substrate. Finally, In conclusion, the applications of superamphiphobic surfaces in areas such as self-cleaning, ice prevention and removal, anti-fogging, anti-adhesion, and antibacterial properties are summarized. The bottlenecks currently limiting their large-scale application are analyzed, along with potential solutions. The future engineering application prospects and development directions of superamphiphobic surfaces are also outlined. Future research should focus on enhancing the durability of superamphiphobic surfaces and exploring novel material synthesis methods and surface treatment technologies to address more complex and demanding application environments. These efforts aim to expand the practical applications of superamphiphobic surfaces and contribute to technological advancements in various fields. |
