The separation of liquid mixture has been studied for a long time. Separationproceeds based on the difference in physical properties including pore size andelectrostatic interaction. Therefore, there are many difficulties in separationof materials having similar size or polarities in physical properties such asethanol-water and 1,4-dioxane-water mixtures. While we still lack a universalgeneralization of these ideas to the separation, pervaporation based on adifference in transport rates by permeability through a membrane by thepermeate was early suggested. Yet there is an existing technical gap to removetrace amounts of organics dissolved in water. Here, we report a novelseparation strategy employing a metamaterial, called meta-separation using theexotic structural property of metamateirals rather than electrostaticcharacteristics. The structural properties of metamaterials provide variousfunctions of super-hydrophobicity based on roughness of surface, the strongcapillary effect based on nanopore, and huge void for great absorption oforganics. It exhibited a water contact angle of 151.3{\deg} and high adhesiveproperty from nanopore. On the other hands, ethanol was immediately absorbed upto 93 wt%. This differences made it possible to quickly and easily eliminateorganics dissolved in water. Furthermore, their applications are expected toachieve functions in environmental remediation, biofuel separation process,etc., without large scale facilities.
