This article describes development of a simple and convenient method to provide stable low-surface-energy coatings on organic surfaces, by designing and synthesizing a surface-reactive molecule 4-azido-N-dodecylbenzamide, which bears an azide group as the reactive surface anchor and an alkyl chain as the hydrophobic tail. After the hydrophobic modification, rough organic surfaces with contact angle of about 0 degrees can change their surface wetting properties from superhydrophilicity to superhydrophobicity, whose contact angles are above 152 degrees and tilt angles lower than 5 degrees. Moreover, by changing the alkyl chain to a PEO segment, a similar concept can be used to adjust the surface wetting properties from hydrophobic (contact angle approximately 130 degrees) to superhydrophilic (contact angle approximately 0 degrees).

通过原位叠氮化物的光反应来调节有机表面的润湿性能。

本文介绍了一种通过设计和合成表面活性分子4-叠氮基-N-十二烷基苯甲酰胺（以叠氮化物基团作为反应性表面锚定剂）来在有机表面上提供稳定的低表面能涂层的简单便捷方法的开发过程。烷基链为疏水尾。疏水改性后，接触角约为0度的粗糙有机表面可以将其表面润湿性从超亲水性更改为超疏水性，其接触角大于152度，倾斜角小于5度。此外，通过将烷基链改变为PEO链段，可以使用类似的概念将表面润湿性从疏水性（接触角约为130度）调整为超亲水性（接触角约为0度）。
