Creating a robust synthetic surface that repels various liquids would have broad technological implications for areas ranging from biomedical devices and fuel transport to architecture but has proved extremely challenging. Inspirations from natural nonwetting structures, particularly the leaves of the lotus, have led to the development of liquid-repellent microtextured surfaces that rely on the formation of a stable air–liquid interface. Despite over a decade of intense research, these surfaces… Expand

Facile approach to design a stable, damage resistant, slippery, and omniphobic surface
Creating a robust omniphobic surface that repels various liquids would have broad technological implications for areas ranging from biomedical devices and fuel transport to architecture. The present… Expand
Fabrics coated with lubricated nanostructures display robust omniphobicity.
TLDR
SLPS-functionalized cotton and polyester fabrics exhibit decreased contact angle hysteresis and sliding angles, omni-repellent properties against various fluids including polar and nonpolar liquids, pressure tolerance and mechanical robustness, all of which are not readily achievable with the state-of-the-art superhydrophobic coatings. Expand
Transparency and damage tolerance of patternable omniphobic lubricated surfaces based on inverse colloidal monolayers.
TLDR
Colloidal templating is employed to design transparent, nanoporous surface structures that are highly defect-tolerant due to its interconnected, honeycomb wall structure, and repellency prevails after the application of strong shear forces and mechanical damage. Expand
Biomimetic self-slippery and transferable transparent lubricant-infused functional surfaces.
TLDR
A facile strategy has been proposed for constructing silica SLIPSs that exhibit transferable performance, which endows the surface with the possibility of meeting the various requirements of different conditions and demonstrates the enormous value of the application of the coatings in many fields.

Robust omniphobic surfaces
TLDR
Four design parameters are proposed that predict the measured contact angles for a liquid droplet on a textured surface, as well as the robustness of the composite interface, based on the properties of the solid surface and the contacting liquid, that allow two different families of re-entrant surfaces to be produced.

Biology is replete with examples of functional structures, whose properties are unmatched in today’s man-made materials. Key features of biological structures are their dynamic nature, responsive… Expand
Quantitative testing of robustness on superomniphobic surfaces by drop impact.
TLDR
The results show how this robustness depends on Young's contact angle θ(0) related to the surface tension of the liquid and that the orientational growth of nanowires is a favorable factor for robustness. Expand
Underwater restoration and retention of gases on superhydrophobic surfaces for drag reduction.
TLDR
This Letter finds surface structures that allow the restoration of a gas blanket from a wetted state while fully immersed underwater and designs a self-controlled gas-generation mechanism that maintains the SHPo condition under high liquid pressures as well as in the presence of surface defects, thus removing a fundamental barrier against the implementation of SHPo surfaces for drag reduction.

Imbibition by polygonal spreading on microdecorated surfaces.
TLDR
Wetting on topographically patterned but chemically homogeneous surfaces is discussed and mechanisms of shape selection during imbibition of the texture are demonstrated, leading to a 'shape' diagram that summarizes observations and suggest rules for a designer's tool box. Expand
Designing Superoleophobic Surfaces
TLDR
It is shown how a third factor, re-entrant surface curvature, in conjunction with chemical composition and roughened texture, can be used to design surfaces that display extreme resistance to wetting from a number of liquids with low surface tension, including alkanes such as decane and octane.

TLDR
It is demonstrated that gecko setae are a self-cleaning adhesive and proposed that the property of self- Cleaning is intrinsic to the setal nanostructure and therefore should be replicable in synthetic adhesive materials in the future. Expand
