仿耐寒竹叶微结构的超疏水防冰表面制备实验设计

Experimental Design for the Preparation of Superhydrophobic Anti-icing Surface by Imitating the Microstructure of Cold-resistant Bamboo Leaves

为了模仿耐寒竹叶的微结构特征,基于润湿性和传热基本理论,通过仿生学方法,开发了一种超疏水防冰表面。利用纳秒激光刻蚀一步法在金属铜表面构建微纳分级结构,再用豆蔻酸溶液对表面进行修饰,从而制备出具有仿耐寒竹叶微结构的超疏水表面,并将其应用于防冰实验。实验结果表明,所设计的仿生样件继承了耐寒竹叶优异的超疏水防冰性能。

This study aims to explore and mimic the microstructural features of cold-resistant bamboo leaves,and design a novel superhydrophobic anti-icing surface.Based on the basic theories of wettability and heat transfer,by using bionic approach,we develop a surface that can effectively inhibit the formation and attachment of ice,thus maintaining its superhydrophobicity in low-temperature environments.Micro-nano hierarchical structure is constructed on the copper surface by one-step nanosecond laser etching,and then the surface is modified by myristic acid solution to prepare a superhydrophobic surface with cold-resistant bamboo leaf microstructure,and it is applied to anti-icing experiments.The research results show that the designed bionic sample inherits the excellent superhydrophobic anti-icing performance of cold-resistant bamboo leaves.
