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… 
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.
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 slippery
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.
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.
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 to
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.
Slippery liquid‐infused porous surfaces: The effect of oil on the water repellence of hydrophobic and superhydrophobic soils
Soil wettability is important for understanding a wide range of earth system processes, from agricultural productivity to debris flows and sediment fan formation. However, there is limited research

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.
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.
Biomimetics in Materials Science: Self-Healing, Self-Lubricating, and Self-Cleaning Materials
This book describes the development of Metallic and metal matrix composite self-healing materials and Thermodynamic foundations of wetting and capillary phenomena, which led to self-cleaning and self-lubrication.
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.
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).
