The hydrophobicity based on the surface formation of microstructures can be effectively applied to such important fields like water corrosion protection, cable protection, aircraft anti-icing and so on. In this paper, the several kinds of hydrophobic function of the copper surfaces were realized by femtosecond laser directly induced microstructures without any other means of chemical treatment, and the influence of temperature on the hydrophobic characteristics of microstructure surfaces and their anti-icing properties where further systematicly studied. Results indicate the hydrophobic surface of micro-nano structure under the low temperature compared with the original surface can postpone the freezing process of water droplets on the surface, and the formation of this phenomenon is related to wettability and morphology of micro-nano structure.
