源于荷叶自清洁效应的超疏水表面已成为材料、仿生等领域的研究热点之一。相对有机高分子材料而言，金属材料超疏水性表面具有更高的耐久性。但晶态金属的“晶粒效应”制约了表面微/纳尺度几何结构的制备。非晶合金在过冷液相区优异的微/纳尺度成形能力，以及较晶态金属更低的表面自由能，使其成为制备超疏水性金属表面的理想材料之一。综述了不同体系非晶合金的表面能；非晶合金表面微/纳尺度几何结构的构造；表面几何结构对疏水性的影响规律及机理；并对非晶合金表面超疏水性进行了展望。
The superhydrophobic surface originated from the lotus leaf has become one of the research highlights in the field of materials and bionics.By comparison with the organic polymer,the super hydrophobic metallic surfaces exhibit much higher durability.However,the “grain size effect”of the crystalline metals restricts the fabrication of surface micro/nano scale geometry.Due to the excellent forming ability in micro/nano scale of a-morphous alloys in the supercooled liquid region,and the lower surface free energy as compared with the crys-talline metals,amorphous alloys has been regarded as an ideal material to fabricate the superhydrophobic metal surface.In this work,the surface free energy of amorphous alloys with different compositions,the fabrication of micro/nano scale surface geometric structure,the influence of surface patterns on the hydrophobicity and the related mechanism are reviewed,finally the prospect of the superhydrophobic amorphous alloy surface is com-mented.
