Practical application of superhydrophobic surfaces is limited by the fragility of nanoscale asperities. Combining chemical etching and anodization, microscale pits and nanoscale pores, instead of the micro and nano protrusions on traditional superhydrophobic surfaces mimicking Lutos leaves, were fabricated on commercially pure aluminum surfaces. After modified by FDTS, the surfaces were superhydrophobic and self-cleaning. The ultrahigh hardness and electrochemical stability of Al2O3 coating endowed the surface excellent mechanical durability and good corrosion resistance. Because the method is scalable, it may find practical application on body panels of automobiles and aircrafts and so on.
超疏水表面的实际应用受到纳米级微凸体脆弱性的限制。通过结合化学蚀刻和阳极氧化工艺，在工业纯铝表面制备出了微米级凹坑和纳米级孔隙，而非传统超疏水表面上模仿荷叶的微米和纳米级凸起。经FDTS修饰后，这些表面具有超疏水性和自清洁性能。Al2O3涂层的超高硬度和电化学稳定性赋予了表面优异的机械耐久性和良好的耐腐蚀性。由于该方法具有可扩展性，它可能在汽车和飞机等的车身面板上找到实际应用。
