摘要:

单分散气泡的自发力学自组装通常在低密度下产生无序泡沫:尽管开尔文泡沫是能量极小结构,但实验上制备此类晶体结构已被证明具有挑战性。本文展示了在不同纤维阵列中鼓泡如何通过引导式力学自组装来调控泡沫结构。利用Steinhardt参数分析固化聚合物泡沫的X射线断层扫描,揭示了开尔文晶体泡沫和六方密排晶体泡沫的清晰特征,为有序层级材料开辟了一条新途径。

英文摘要:

Spontaneous mechanical self-assembly of monodisperse bubbles generally leads to disordered foams at low density: producing crystalline structures such as Kelvin foams has proven to be challenging experimentally, despite them being a minimum of energy. Here we show how bubbling in different fiber arrays controls foam architectures through a guided mechanical self-assembly. Analyzing X-ray tomography scans of solidified polymer foams using Steinhardt's parameters highlights clear signatures of Kelvin and hexagonal close packing crystalline foams, opening a novel route towards ordered hierarchical materials.
