In recent years the research community has paid significant attention to geometrically engineered materials. These materials derive their unique properties from their structure rather than their chemistry alone. Despite their success in the laboratory, the assembly of such soft functional materials remains an outstanding challenge. Here, we propose a robust fluid-mediated route for the rapid fabrication of soft elastomers architected with liquid inclusions. Our approach consists of depositing water drops at the surface of an immiscible liquid elastomer bath. As the elastomer cures, the drops are encapsulated in the polymer and impart shape and function to the newly formed elastic matrix. Using the framework of fluid mechanics, we show how this type of composite material can be tailored.

在液态弹性体上印刷

近年来，研究界对几何工程材料给予了极大的关注。这些材料的独特之处在于其结构而不是化学性质。尽管它们在实验室中取得了成功，但这种软功能材料的组装仍然是一个巨大的挑战。在这里，我们提出了一种鲁棒的流体介导途径，可以快速制造带有液体夹杂物的软弹性体。我们的方法包括在不混溶的液态弹性体浴液表面沉积水滴。随着弹性体的固化，液滴被包裹在聚合物中，并赋予新形成的弹性基质形状和功能。使用流体力学的框架，我们展示了如何定制这种类型的复合材料。
