Liquid-impregnated porous polypropylene surfaces for liquid repellency
Journal of Colloid and Interface Science, 2017Polypropylene is a popular plastic material used in consumer packaging. It would be desirable if such plastic containers were liquid repellent and not so easily fouled by their contents. Superomniphobic surfaces typically work by keeping the fouling liquid in a metastable state, with trapped pockets of air between the substrate and the liquid.

CHAPTER 13. Droplet Manipulation on Liquid-Repellent Surfaces
2016The low friction experienced by droplets on a liquid-repellent surface allows for facile and precise manipulation of the droplets, and could open routes for droplet microfluidics, lab-on-a-chip systems, and other applications. This review first discusses the principles of droplet friction.

Liquid-repellent surface heals itself
C&EN Global Enterprise, 2018Researchers have developed a new kind of liquid-repelling coating that can withstand harsh conditions and heal itself when damaged (ACS Appl. Mater. Interfaces 2018, DOI: 10.1021/acsami.8b10838).

Super-liquid-repellent coating on the carbon steel surface
Surface and Coatings Technology, 2013Abstract In this study, the spray coating method was used to fabricate a superamphiphobic coating with extremely high contact angles of 170°, 159.7° and 124° and low sliding angles of 1°, 4° and 10° for DI water, ethylene glycol and fuel oil droplets, respectively.

Super-liquid-repellent (SLR) surfaces based on surface micro/nanotextures are generally regarded as "non-wettable", though careful examination shows that residual microdroplets remain atop surface textures upon drop shedding-off. Despite its great importance, the origin of microscopic liquid residues remains poorly explored, and how to suppress residue

Superhydrophobic surfaces in the Cassie-Baxter wetting state retain an air layer at the surface which prevents liquid water from reaching into the porous surface structure. In this work we explore how addition of ethanol, which reduces the surface tension, influences the wetting properties of superhydrophobic and smooth hydrophobic surfaces.

Liquid-repellent surfaces based on nanostructured silicon substrates
2017This work focuses on the preparation of liquid repellent surfaces. We follow two fundamentally different biomimetic approaches to reach this goal, Cassie-Baxter systems and SLIPS (Slippery Liquid Infused Porous Surfaces) systems. Cassie-Baxter systems are commonly found in nature, with the lotus leaf as the most popular example.

Liquid-repellent surfaces for frictional drag reduction & noise attenuation [PDF]
, 2018 Skin-friction drag is a major source of energy dissipation in marine vehicles. In addition, self-induced noise generated by turbulent boundary layer can strongly limit the operation of on-board sensors. Therefore, designing surfaces with friction drag reduction and vibration control properties is a research topic of great interest for the marine ...
