Metal surface ultra -hydrophobic has important potential applications in the fields of self -cleaning, anticorrosion, resistance, and ice prevention.At present, the realization of the super -hydrophobic performance of the metal surface still depends on the traditional dual coordinated design ideas. This design that rely on adhesive coating can easily suffer from erosive ions in the actual corrosive environment (such as seawater), which will cause coating to coat Risks such as decomposition, looseness and peeling, which trigger a significant decline in ultra -hydrophobic chemical durability, which is a common problem for many practical applications for many practical applications.
Yang Jianjun team creatively proposed a research method that combined the combination of femtosecond laser elements doped by the micro -nano structure and the low temperature annealing of the cycle. The bionic ant acupoint structure dominated by the secondary phase, successfully realized the high -efficiency and stable self -initiating ultra -hydrophobic effect.Experimental measurement results show that the surface of the metal sample can still maintain a good ultra -hydrophobic performance even after experiencing up to 2000 hours of corrosive saline.Not only that, the corrosion resistance of this structure is also particularly prominent. After a strong electrochemical reaction test, the ultra -hydrophobic characteristics of the material surface can still be maintained.This breakthrough has not only opened up a broad prospect for ultra -hydrophobic fields, but also provides a new research idea for the design and development of high -performance materials based on atomic standards.
