The omniphobicity includes both hydrophobic and oleophobic properties. Hence, they have repelpency even with low surface tension liquids. In decades, researchers have fabricated super-hydrophobic surface by roughening the systen. Nowadays, however, necessity of omniphobicity rises for advanced technologies such as self-cleaning, anti-fingerprint. In particular, springtail inspires researchers with its intrinsic omniphobicity. Therefore, some studies have reported about the its surface for revealing origin. They observed skin is composed of micro-roughness and mushroom-like nanostructures. They showed also surface has not only omniphobicity, but high stability upon pressure. However analysis in system is still challenging. Because this kind of dual-scale structure is not fabricated yet and hard to control. In this report, we fabricated dual-scale structure with micro-scale wrinkle and nanostructures with high tunability. We can both parameters simultaneously. We confirmed wetting behaviors of low surface tension liquids with different conditions of system. Further analysis and robustness test may provide new criteria for designing next-generation omniphobic surface. |
