摘　　要：传统表面科学实验教学内容大多是演示性的,缺乏材料界面微结构和性质调控方法,尤其在超疏水表面的高效制备方面。本实验利用高效的巯基-迈克尔加成点击反应,在聚对苯二甲酸乙二醇酯(PET)纤维织物表面快速构筑了荷叶仿生微结构和性质的超疏水涂层,探索了表面微结构对超疏水性能的影响。该实验教学项目使学生能直观感受到超疏水表面的设计原理,加深对材料表面润湿性机理的理解和认识,同时培养学生追求科学真理的热情。The traditional surface science experimental teaching contents were mostly demonstrative and lacked the adjusting approaches for elaborating the surface microstructure and functional property,especially in the domain of efficient preparation of superhydrophobic surfaces.In this experiment,lotus leaf biomimetic superhydrophobic surfaces were rapidly constructed via the efficient Thiol-Michael addition click reaction and coated on the commercial poly(ethylene terephthalate)(PET)woven fabric.The influence of the surface microstructure on the superhydrophobic performance of the coating on PET fabric was then investigated.This experiment teaching project could enable the undergraduate students to perceive the designing principles of superhydrophobic surfaces,deepen students’understanding of the wettability mechanism of the material surface,and cultivate their passion for pursuing scientific truth.
