材料表面的润湿是一个重要的课题，目前正在深入研究各种实际应用，但大多数以前的研究采用事后分析方法。幸运的是，环境扫描电子显微镜（ESEM）的最新发展意味着可以在其天然状态下观察水合样品以及动态表面反应。本文采用原位环境扫描电镜（ESEM）观察方法，研究了湿润过程中竹叶近轴面和远轴面水滴的微观生长动态。我们的研究结果表明，由于近轴面和远轴面之间的结构差异，水滴在两侧的生长是相当不同的。此外，还定量地讨论了水滴在不同BML表面上的生长动力学。这一概念性研究为理解润湿行为提供了一条直接的途径，其结果可能为进一步研究仿生材料铺平道路。材料表面的润湿是一个重要的课题，目前正朝着各种实际应用方向进行深入研究，但大多数以前的研究都采用事后分析方法。幸运的是，环境扫描电子显微镜（ESEM）的最新发展意味着可以在其天然状态下观察水合样品以及动态表面反应。本文采用原位环境扫描电镜（ESEM）观察方法，研究了湿润过程中竹叶近轴面和远轴面水滴的微观生长动态。我们的研究结果表明，由于近轴面和远轴面之间的结构差异，水滴在两侧的生长是相当不同的。此外，还定量地讨论了水滴在不同BML表面上的生长动力学。这一概念性研究为理解润湿行为提供了一条直接的途径，其结果可能为进一步研究生物启发的材料铺平道路。
The wetting of material surfaces is an important topic and is now being intensively investigated toward various practical applications, yet most previous studies have adopted postmortem methods. Fortunately, the recent development of environmental scanning electron microscopy (ESEM) means that hydrated samples can be observed in their native state, as well as dynamic surface reactions. Here, we use in situ ESEM observation to explore the microscopic growth dynamics of water droplets on adaxial and abaxial surfaces of Bambusa multiplex leaf (BML) during wetting. Our results show that, due to the dramatic structural differences between adaxial and abaxial surfaces, the growth of water droplets on the two sides is quite different. Furthermore, the growth kinetics of water droplets on different BML surfaces are quantitatively discussed. This conceptual study demonstrates a straightforward pathway to understanding the wetting behavior, and the results may pave the way for further research on bio-inspired materials.The wetting of material surfaces is an important topic and is now being intensively investigated toward various practical applications, yet most previous studies have adopted postmortem methods.
