摘要：

选取常见的多种绿色植物作为实验对象，利用手机和显微放大镜获取接触角图像，并采用原创Python程序计算接触角来实施科普实验。并根据不同叶片的接触角现象及其表面结构特点，进一步利用玻璃片、Zn片等材料，通过简单方式模拟叶片微观结构，得到不同润湿性能的仿生表面材料。从叶片接触角现象到表面微观结构的探索模拟，本实验站在界面化学的角度揭示结构与功能的关系，践行化学源于生活的理念。

Abstract:

In this popular science experiment, a variety of common green plants were selected for the experiment. The contact angle images were obtained using a mobile phone and microscopic magnifier; the original Python program was used to calculate the contact angle. According to the contact angle phenomenon of different leaves and their surface structure characteristics, glass sheets, Zn sheets, and other materials have been adopted to simulate the microstructure of leaves in a simplified manner. Additionally, bionic surface materials were obtained with different wetting properties. From the application of this blade contact angle phenomenon to the exploration and simulation of surface microstructures, this experiment revealed the relationship between the leaf structure and function from the perspective of interface chemistry and investigated the concept that chemistry comes from life.
