摘　　要：基于微结构表面形成的疏水特性可以有效应用于水腐蚀防护、电缆防护、飞机防冰等重要领域。研究中,不借助其他化学处理手段,仅通过飞秒激光直接制备了多种疏水功能特性微纳结构铜表面,并系统研究了温度对微纳结构表面的疏水特性影响及抗结冰性能。结果表明,这些疏水微纳结构表面在低温下与原表面相比都能有效延缓水滴的结冰过程,这一现象的产生与其表面润湿性能及微纳结构形貌有关。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.
