Lubricated surfaces have shown promise in numerous applications where impinging foreign droplets must be removed easily; however, before they can be widely adopted, the problem of lubricant depletion, which eventually leads to decreased performance, must be solved. Despite recent progress, a quantitative mechanistic explanation for lubricant depletion is still lacking. Here, we first explained the shape of a droplet on a lubricated surface by balancing the Laplace pressures across interfaces… 

Droplets on lubricated surfaces: The slow dynamics of skirt formation

A key question in the interaction of droplets with lubricated and liquid-infused surfaces is what determines the apparent contact angle of droplets. Previous work has determined this using measured

Droplet Morphology and Mobility on Lubricant-Impregnated Surfaces: A Molecular Dynamics Study.

It is discovered that the four possible stable states on SLIPS predicted by theoretical studies can be extended to eight states by considering the effects of lubricant thickness and surface geometry in addition to the interfacial tension and surface wettability.

Droplets on Lubricant Infused Surfaces: The slow dynamics of skirt formation

A key question in the interaction of droplets with liquid-infused surfaces is what determines the apparent contact angle of droplets. Previous work has used measured values of the skirt geometry

The Effect of Lubricant Viscosity on Nucleation for Water Condensation on Lubricant-Infused Surfaces

Lubricant-infused surfaces (LIS) can promote stable dropwise condensation and improve heat transfer rates due to a low nucleation energy barrier and high droplet mobility. Yet nucleation dynamics on

Bidirectional motion of droplets on gradient liquid infused surfaces

The current paradigm of self-propelled motion of liquid droplets on surfaces with chemical or topographical wetting gradients is always mono-directional. In contrast, here, we demonstrate

Nanobubbles explain the large slip observed on lubricant-infused surfaces

It is revealed that infused nanostructured Teflon wrinkles induce large interfacial slip due to the spontaneous nucleation of surface nanobubbles, a mechanism likely to occur on most rough infused surfaces.

Capillary Balancing: Designing Frost-Resistant Lubricant-Infused Surfaces

Three-dimensional spatial analysis via confocal microscopy reveals that lubricants in optimally structured Nano-SLIPS are not affected throughout condensation, extreme frosting, and traverse ice-shearing tests, demonstrating a design principle for next-generation anti-icing surfaces.

Capillary Bridges on Liquid-Infused Surfaces.

Two-component capillary bridges formed when a liquid droplet is placed in between two liquid-infused surfaces (LIS) are numerically studied and can be tuned to increase the effective capillary adhesion strength by manipulating the lubricant pressure, Neumann angle, and wetting contact angles.

Enhanced Water Nucleation and Growth Based on Microdroplet Mobility on Lubricant-Infused Surfaces.

It is revealed that during water condensation on LISs, the smallest visible droplets predominantly emerge in oil-poor regions due to a lower nucleation free-energy barrier, and two dominant regimes that influence the condensation efficiency are introduced: mobility-limited and coalescence-limited.



Oleoplaning droplets on lubricated surfaces

Recently, there has been much interest in using lubricated surfaces to achieve extreme liquid repellency: a foreign droplet immiscible with the underlying lubricant layer was shown to slide off at a

Direct observation of drops on slippery lubricant-infused surfaces.

This work image the shape of drops on lubricant-infused surfaces by laser scanning confocal microscopy and reveals fundamentally different processes at the front and rear of moving drops.

Shape of a sessile drop on a flat surface covered with a liquid film.

A sessile drop of a nonvolatile (ionic) liquid which is embedded in a slowly evaporating lubricant film (n-decane) on a horizontal, planar solid substrate is studied and the size of the meniscus is particularly relevant because it affects sliding angles of drops on lubricant-infused surfaces.

Boundary lubrication under water

It is shown that the frictional stress between two sliding surfaces bearing surfactant monolayers may decrease, when immersed in water, to as little as one per cent or less of its value in air (or oil).

Drop mobility on chemically heterogeneous and lubricant-impregnated surfaces

Abstract Controlling the motion of liquid drops in contact with a solid surface has broad technological implications in many different areas ranging from textiles to microfluidics and heat

Delayed lubricant depletion on liquid-infused randomly rough surfaces

Abstract In this study, pressure drops on liquid-infused superhydrophobic surfaces were measured through a microchannel. A number of different superhydrophobic surfaces were prepared and tested.

Droplet mobility on lubricant-impregnated surfaces

Non-wetting surfaces containing micro/nanotextures impregnated with lubricating liquids have recently been shown to exhibit superior non-wetting performance compared to superhydrophobic surfaces that

Evaporation of Sessile Droplets on Slippery Liquid-Infused Porous Surfaces (SLIPS).

For the SLIP surfaces, it was found that the evaporation of small sessile droplets followed an ideal constant contact angle mode where the apparent contact angle was defined from the intersection of the substrate profile with the droplet spherical cap profile.

Shear-driven failure of liquid-infused surfaces.

This work examines shear-driven drainage of liquid-infused surfaces with the goal of understanding and thereby mitigating this failure mode, and establishes the geometric surface parameters governing fluid retention and shows how these parameters can describe even random substrate patterns.

Liquid-infused nanostructured surfaces with extreme anti-ice and anti-frost performance.

Results indicate that SLIPS is a promising candidate for developing robust anti-icing materials for broad applications, such as refrigeration, aviation, roofs, wires, outdoor signs, railings, and wind turbines.
