논문초록 Superomniphobicity can be generated by fabricating reentrant structures on surfaces. These structures can consist of different shapes (e.g. mushroom shape or inverse trapezoids) whose characteristic, the Cassie-Baxter state, is causing superomniphobicity. Due to the narrow region on structures bottom, reentrant structures can be fragile towards mechanical load or shear. Therefore, it is still challenging to provide durability for superomnipohobic reentrant structures under the exposure of external mechanical stress. Here, a facile method for obtaining a durable micro-sized hyperbola structure is proposed, by applying a photocurable viscous liquid around micro-pillars, utilizing capillary wrapping. The micro-hyperbola structure shows high robustness that maintains omniphobic, even after carrying out physical stress tests (rubbing and friction tests). The here presented structure has huge potential for practical application in various fields which require superomniphobic surfaces.
