A dual underliquid superlyophobic surface in organic media for on-demand separation of immiscible organic liquid mixtures

High -efficiency on-demand separation is still extremely rare for treating immiscible organic liquid mixtures. Herein, we develop a facile and scalable protocol to prepare a practical dual underliquid superlyophobic surface for polar or nonpolar liquids in opposite lquid media. The challenging on-demand organic liquid separation can be successfully realized.
