Technical Field

The invention provides a novel method for preparing a super-hydrophobic structure on the surface of an amorphous alloy, and provides a novel technical scheme for efficiently preparing the super-hydrophobic structure on the surface of the amorphous alloy in a large area. The method has great application value in the aspects of self-cleaning of the surface of the amorphous alloy, anti-icing and microfluid control.
Background
Compared with the traditional crystalline alloy, the amorphous alloy has no crystal boundary and dislocation, so that the amorphous alloy has excellent fracture strength, elastic limit and corrosion resistance, and has wide application in military, biomedicine and flexible electronics. If the surface of the amorphous alloy can realize super-hydrophobicity, the application range of the amorphous alloy can be further widened. The micro-nano structure on the surface of the material is an important factor for realizing the super-hydrophobicity of the surface of the material, and the micro-nano structure can be constructed on the surface of the amorphous alloy through electrochemical corrosion, but the repetition precision is low; the processing of the micro-nano structure on the surface of the amorphous alloy can be accurately realized through a nano-imprinting mode, but the processing process is complex and the efficiency is low. By integrating the consideration of the repetition precision and the processing efficiency, in recent years, the ultrafast laser etching technology is widely applied to the preparation of the amorphous alloy surface micro-nano structure. The femtosecond laser and the picosecond laser can realize the processing of the amorphous alloy surface micro-nano structure with high efficiency and high precision, but the equipment cost is high, and the equipment is not beneficial to industrial large-scale application, so that the low-price nanosecond laser is gradually applied to the processing of the amorphous alloy surface micro-nano structure. In addition, another important factor for realizing the superhydrophobicity of the material surface is that the material surface has low surface energy, however, at present, the superhydrophobicity of the amorphous alloy surface is realized by modifying the micro-nano structure of the amorphous alloy surface by using a chemical reagent and reducing the surface energy of the amorphous alloy surface, the superhydrophobic surface obtained by the method has a complex process and high cost, and the used chemical reagent is not beneficial to environmental protection. In summary, there is an urgent need for a new method for preparing amorphous alloy superhydrophobic surface with high efficiency, simple steps, high precision and low cost, and large area.
