| 摘要: |
| 仿猪笼草超滑表面具有疏液性和防污性等优异性能。然而仿生超滑表面的润滑油膜受损后，其超滑性能会被破坏， 因此制备具有自修复性能的仿生超滑表面对于解决其耐久性差的问题至关重要。首先采用阳极氧化法在铝合金基体表面制备锥形微结构，然后经过全氟硅烷进行低能修饰，最后往微结构间隙中注入全氟聚醚、低黏度硅油和高黏度硅油三种不同的润滑油，得到三种仿生超滑表面。水滴在三种仿生超滑表面的接触角分别为~116°、~105°、~103°，滑动角分别为~10°、~10°、~9°。试验结果表明，全氟聚醚和低黏度硅油的仿生超滑表面比高黏度硅油的仿生超滑表面具有更优的自清洁性和防污性，可以有效地预防污染物堆积造成的疏液性失效。此外，全氟聚醚与低黏度硅油的仿生超滑表面呈现较好的热辅助自修复性，修复后的疏水性与新制备样品基本一致；高黏度硅油仿生超滑表面只表现出一定的自修复能力，修复后与新制备样品的疏水性存在差异。所制备出的具有热辅助自修复功能的铝合金基底仿生超滑涂层，在海洋生物污损防护方面具有潜在的应用前景，并为克服传统仿生超滑表面使用耐久性差的问题提供了解决思路。 |

| Abstract: |
| The super slippery surface inspired by Nepenthes shows excellent properties such as liquid repellency and antifouling. However, when the lubrications film on the bionic super slippery surface is damaged, its super slippery property will be destroyed. Therefore, preparation of bionic super slippery surfaces with self-healing properties is crucial to solve the problem of poor durability. This paper first uses anode oxidation method to prepare a tapered microstructure on the surface of the aluminum alloy substrate, then uses perfluorosilane for low-energy modification, and finally injects three different lubrications of perfluoropolyether,low-viscosity silicone oil and high-viscosity silicone oil into the microstructure gap. Three bionic super slippery surfaces are obtained. The contact angles of water droplets on these three bionic super slippery surfaces are ~116°, ~105° and ~103°, respectively, and the sliding angles are ~10°, ~10°, and ~ 9°, respectively. The experimental results indicate that the bionic super slippery surfaces with perfluoropolyether and low-viscosity silicone oil show better self-cleaning and antifouling properties than the bionic super slippery surface with high-viscosity silicone oil, which can effectively prevent the failure of liquid repellency caused by the accumulation of pollutants. In addition, the bionic super slippery surface with perfluoropolyether and low-viscosity silicone oil show excellent thermal-assisted self-healing property, and the hydrophobicity after heal is basically the same as that of newly prepared samples. However, the bionic super slippery surface with high-viscosity silicone oil only shows a certain degree of self-healing, and the hydrophobicity of the healed sample is different from that of the newly prepared sample. Therefore, the prepared bionic super slippery surfaces on aluminum alloy substrate with thermally assisted self-healing property would show potential application prospect in marine anti-biofouling. A solution is providef for overcoming the poor durability of the traditional bionic super slippery surface. |
