在这里，我们报告了一种类型的铝基冷凝液微滴自推进（CMDSP）功能薄膜的基础上，可控的阳极氧化铝杆盖纳米孔的制造，这可以通过一个三步的方法实现的基础上巧妙地结合成熟的硬阳极氧化，温和阳极氧化和化学蚀刻技术。这种表面纳米工程的策略被验证是可行的，通过我们的示例性实验和扫描电子显微镜表征。经氟硅烷修饰后，表面纳米结构可以诱导小尺度冷凝液微滴的有效自跳跃，特别是在50 μm以下。这项工作提供了一个途径，开发CMDSP铝表面的自清洁，防霜，防结露功能。
Here, we report a type of aluminum-based condensate microdrop self-propelling (CMDSP) functional films based on the controllable fabrication of anodic alumina rod-capped nanopores, which can be realized by a three-step method based on the skillful combinations of well-established hard anodization, mild anodization and chemical etching techniques. Such a surface nanoengineering strategy is verified to be feasible via our exemplified experiments and scanning electronic microscopy characterizations. After fluorosilane modification, the surface nanostructure can induce the efficient self-jumping of small-scale condensate microdrops, especially below 50 μm. This work offers an avenue for developing CMDSP aluminum surfaces with self-cleaning, antifrosting, and antidewing functions.
