Materials science: Slippery when wetted

  title={Materials science: Slippery when wetted},
  author={Michael Nosonovsky},
The slick interior of the pitcher plant has inspired a slippery material possessing self-lubricating, self-cleaning and self-healing properties. The secret is to infuse a porous material with a liquid that repels oils and water. See Letter p.443 Inspired by the insect-eating Nepenthes pitcher plant, which snares its prey on a surface lubricated by a remarkably slippery aqueous secretion, Joanna Aizenberg and colleagues have synthesized omniphobic surfaces that can self-repair and function at… Expand

Biomimetic Self-Cleaning Anisotropic Solid Slippery Surface with Excellent Stability and Restoration.
This ASSS material is demonstrated to be of excellent stability compared with SLIPS as the solid lubricant cannot be lost and stain the contacting surfaces, and exhibits outstanding acid and alkali corrosion resistance and restoration capability upon physical damage. Expand
Slippery Properties and the Robustness of Lubricant-impregnated Surfaces
Inspired by nepenthes pitcher plants, Lubricant-Impregnated Surfaces (LISs) are surfaces with lubricant infused in the textures which form slippery interfaces. In this paper, we investigated slipperyExpand
High Temperature durability of Oleoplaned Slippery Copper Surfaces.
The findings suggest that these new substrates can be used for fabricating low maintenance surfaces for high temperature applications or even where the surface undergoes repeated thermal cycles like heat exchanger pipes, utensils, engine casings, outdoor metallic structures. Expand
Lotus Effect and Friction: Does Nonsticky Mean Slippery?
The relevant adhesion mechanisms and parameters are reviewed and the complex interrelation between friction and wetting is discussed, which is crucial for the design of biomimetic functional surfaces. Expand

LISSs with slight hydrophobicity yield slippery properties, resulting in an order of magnitude lower ice adhesion compared to SHSs, and one-production strategy can be broadly used to design icephobic materials. Expand
A stable solid slippery surface with thermally assisted self-healing ability
The volatilization, migration and contamination of lubricating fluids has seriously affected the durability of slippery liquid-infused porous surfaces (SLIPSs) and greatly limited their applications.Expand
What are the design principles, from the choice of lubricants and structures to the preparation method, for a stable slippery lubricant-infused porous surface?
Despite decades of research, superhydrophobic surfaces still rely on a stable air layer that is plagued with problems, such as poor pressure stability, the inability to self-heal, and the failure toExpand
Synthesis and characterization of omniphobic surfaces with thermal, mechanical and chemical stability
A durable slippery liquid-infused porous surface (SLIPS) omniphobic coating was developed that can be simply applied to various substrates to repel water, coffee, red wine and cooking oils. TheExpand
Durable deicing lubricant-infused surface with photothermally switchable hydrophobic/slippery property
Abstract Lubricant infused surfaces (LISs) are promising platforms to address the icing problems, but their long-term stability remains a significant challenge. In this study, a durable LIS withExpand
A thermal-driven self-replenishing slippery coating
Abstract The durability of the traditional lubricant impregnated surfaces was limited, due to the instability of the infused liquid lubricants and the mechanical weakness of the underlying textures.Expand


Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity
A strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency, applicable to various inexpensive, low-surface-energy structured materials (such as porous Teflon membrane). Expand

It is demonstrated that the two factors preventing insect attachment to the peristome, i.e., water lubrication and anisotropic surface topography, are effective against different attachment structures of the insect tarsus. Expand
Purity of the sacred lotus, or escape from contamination in biological surfaces
It is shown here for the first time that the interdependence between surface roughness, reduced particle adhesion and water repellency is the keystone in the self-cleaning mechanism of many biological surfaces. Expand
Robust omniphobic surfaces
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.
