光学透明的液体大理石是由水和甘油滴嵌入表面处理的气相二氧化硅纳米粒子。在压缩和拉伸载荷条件下，这种液体大理石的机械鲁棒性显示出大于由微粒聚（聚乙烯）制成的类似大理石。使用液体蒸发数据和环境扫描电子显微镜图像，我们表明，它们的鲁棒性可能归因于自组装的液体-蒸汽界面上的纳米颗粒弹性薄膜。(c)2008年美国物理学会。
Optically transparent liquid marbles were made from water and glycerol drops embedded in surface-treated fumed silica nanoparticles. The mechanical robustness of such liquid marbles is shown to be greater than similar marbles made from microparticulate poly(tetrafluoroethylene), both under compressive and tensile loading conditions. Using liquid evaporation data and environmental scanning electron microscope images, we demonstrate that their robustness may be attributed to a nanoparticulate elastic thin film that self-assembles on the liquid-vapor interface.
