当液体蒸发时，潮湿的纤维结构，如纳米管地毯或宏观刷子，往往会自我组装成束。聚集过程依赖于液体桥提供的毛细管吸引力和结构刚度带来的恢复扭矩之间的平衡。人们发现，最终的自组织结构是由小束成对成大束的级联反应形成的。我们首先在宏观尺度和理论上描述了单对纤维的实验情况，然后将这种描述推广到更复杂的3D组件。最后，我们从文献中展示了我们的结果与微观尺度实验的相关性。中国人民解放军版权所有，2007。
Wet fibrous structures such as nanotube carpets or macroscopic brushes tend to self-assemble into bundles when the liquid evaporates. The aggregation process relies on a balance between capillary attraction provided by liquid bridges and restoring torque due to structure stiffness. The final self-organized structure is found to result from a cascade of pairing of smaller bundles into bigger ones. We first describe, both experimentally at a macroscopic scale and theoretically, the case of a single pair of fibers and then generalize this description to more complex 3D assemblies. We finally show the relevance of our results to micro-scale experiments from the literature. Copyright (C) EPLA, 2007.
