Drying-induced patterns, “meniscus splitting”, are introduced through a series of experiments using self-assembled polysaccharides. When physicochemical factors such as the geometry of the evaporative air–liquid interface are controlled, the depositing polymer bridges the gap between two substrates to create multiple nuclei at specific positions for membrane growth. These phenomena were first discovered by our group based on viscous fingering, known as tears of wine . By developing interfacial instability, meniscus splitting causes partitioning of a space by membranes, similar to dissipative structures seen in nature, “from one space into multiple spaces.” In the field of advanced biomimetic materials, the method of convective meniscus splitting would be useful for devising a powerful strategy for the preparation of hierarchically self-assembled materials from a variety of polymeric materials.

干湿两用：从多糖和水的混合物中分离出弯液面

通过一系列使用自组装多糖的实验引入了干燥诱导的模式，即“弯液面分裂”。当物理化学因素（如蒸发气液界面的几何形状）受到控制时，沉积聚合物会桥接两个基材之间的间隙，从而在膜生长的特定位置产生多个核。这些现象是我们小组根据粘性指法首先发现的，称为酒的眼泪。通过产生界面不稳定性，弯月面分裂会导致空间被膜分隔，类似于自然界中看到的耗散结构，“从一个空间到多个空间”。在先进仿生材料领域，对流弯月面分裂的方法将有助于设计一种强大的策略，用于从各种聚合物材料制备分层自组装材料。通过使用自组装多糖作为制备先进仿生材料的方法的一系列演示，引入了干燥诱导的模式，即“弯月面分裂”。在物理化学因素的控制下，沉积聚合物桥接两个基材之间的间隙，在特定位置形成多个核，用于膜生长。通过发展界面不稳定性，弯月面分裂导致空间的分区，类似于自然界中看到的耗散结构，从一个空间到多个空间。”通过一系列使用自组装多糖作为制备先进仿生材料的方法的演示进行介绍。在物理化学因素的控制下，沉积聚合物桥接两个基材之间的间隙，在特定位置形成多个核，用于膜生长。通过发展界面不稳定性，弯月面分裂导致空间的分区，类似于自然界中看到的耗散结构，从一个空间到多个空间。”通过一系列使用自组装多糖作为制备先进仿生材料的方法的演示进行介绍。在物理化学因素的控制下，沉积聚合物桥接两个基材之间的间隙，在特定位置形成多个核，用于膜生长。通过发展界面不稳定性，弯月面分裂导致空间的分区，类似于自然界中看到的耗散结构，从一个空间到多个空间。
