Abstract Superomniphobic surfaces inspired by nature have been studied for decades. Recently, the development of liquid‐repelling has moved from fabrication artificial structures to real applications that address friction associated with clothes, paper, and skin. To superoleophobicity, re‐entrant such as mushrooms or inverse trapezoids suggested. However they can be mechanically fragile, especially under shear stress, because bottom region is narrow. Here, a facile method obtain new...
Wicking in porous media, such as the spreading of ink on paper or absorption moisture by fabric, occurs when water interacts with hydrophilic materials through capillary action and evaporation. The directional nature wicking phenomenon can be leveraged for various advanced applications, including enhanced heat transfer, colorimetric devices, energy harvesting, microfluidics. Herein, crack generation is used to induce anisotropic isolated mesoporous strips. strips are fabricated transforming...
In article number 2010053, Kee-Youn Yoo, Hyunsik Yoon, and co-workers propose a facile method to obtain new re-entrant structures, namely, micro-hyperbola by wetting photocurable viscous liquid around micropillars capillary force. The structure demonstrates robust omniphobicity even after rubbing abrasion tests. superoleophobicity of the structures enables their use in practical superomniphobic applications that undergo shear forces.
