两步法制备仿生超疏水表面的实验设计

受自然界荷叶等表面超疏水现象的启发,结合科研成果,基于固-液界面润湿性相关的理论知识,将超疏水铜网表面的结构设计、制备及其在油水分离中应用研究引入到实验教学中。利用电化学沉积和化学还原两步法在铜网表面构建粗糙的微纳米结构,再将表面以正十二硫醇修饰,制备具有超疏水特性的铜网,将其应用于油水分离。另外,在实验课程中设置结果的分析讨论环节,巩固和验证理论知识点的同时加强学生对实验细节的观察能力。将科研成果回馈教学,这对于丰富教学实验项目、培养学生创新思维、提高学生学习效率、培养复合型人才具有重要的意义。

Design of Bio-inspired Superhydrophobic Surfaces by Two-step Method

Inspired by the superhydrophobic behavior of lotus leaf,combined with scientific research results,and based on the theory related to the wettability of the solid-liquid interface,the design,preparation and application of superhydrophobic surfaces are introduced into the teaching experiment.In this experiment,a superhydrophobic copper mesh is fabricated using electrochemical deposition and chemical reduction in conjunction with the modification of n-dedecanethiol on its surface.The as-prepared superhydrophobic copper mesh is used to separate the mixture of water and oil.In addition,discussion section is introduced to consolidate and verify the theory of the wettability while enhance students’observation skill for the experimental details.Through this experiment,the state-of-the-art scientific research is employed to benefit the teaching via enriching the experimental teaching,enhancing the students’learning efficiency and cultivating the comprehensive talents.
