通过非平凡屈曲的各向异性胶体

Anisotropic colloids through non-trivial buckling

Catherine Quilliet, Carmen Zoldesi, Christophe Riera, Alfons Van Blaaderen, Arnout Imhof

摘要:

本文介绍了胶体颗粒屈曲的实验、理论和数值研究进展。通过乳液模板法制备的充油薄壳在水和乙醇的混合物中表现出屈曲,这是由于核在外部介质中溶解。这导致构象与一个单一的凹陷,无论是轴对称或多边形取决于壳的几何特征。这些构象可以在理论上和/或数值上再现的均匀的球形薄壳的弯曲和拉伸弹性的模型,提交各向同性的外部压力。

英文摘要:

We present a study on buckling of colloidal particles, including experimental, theoretical and numerical developments. Oil-filled thin shells prepared by emulsion templating show buckling in mixtures of water and ethanol, due to dissolution of the core in the external medium. This leads to conformations with a single depression, either axisymmetric or polygonal depending on the geometrical features of the shells. These conformations could be theoretically and/or numerically reproduced in a model of homogeneous spherical thin shells with bending and stretching elasticity, submitted to an isotropic external pressure.
