Designing superoleophobic surfaces.
Understanding the complementary roles of surface energy and roughness on natural nonwetting surfaces has led to the development of a number of biomimetic superhydrophobic surfaces, which exhibit apparent contact angles with water greater than 150 degrees and low contact angle hysteresis. However, superoleophobic surfaces-those that display contact angles greater than 150 degrees with organic li...
متن کاملWetting and friction on superoleophobic surfaces
This article describes the physics of superoleophobic surfaces, combining a recently developed free-energy approach and finite element modeling. We start by investigating the peculiar wetting behavior of such surfaces, originating in their “re-entrant” geometry, and discussing a specific mechanism for the “filling transition”, leading to the loss of superoleophobicity. We then focus on their fr...
متن کاملSuperoleophobic surfaces through control of sprayed-on stochastic topography.
The liquid repellency and surface topography characteristics of coatings comprising a sprayed-on mixture of fluoroalkyl-functional precipitated silica and a fluoropolymer binder were examined using contact and sliding angle analysis, electron microscopy, and image analysis for determination of fractal dimensionality. The coatings proved to be an especially useful class of liquid repellent mater...
متن کاملSolution Spraying of Poly(methyl methacrylate) Blends to Fabricate Micro-textured, Superoleophobic Surfaces
We describe a simple technique to prepare superhydrophobic and superoleophobic micro-textured surfaces by spray coating a blend of poly(methyl methacrylate) (PMMA) and the low surface energy molecule 1H,1H,2H,2H-heptadecafluorodecyl polyhedral oligomeric silsesquioxane (fluorodecyl POSS, γsv ≈ 10 mN/m) using an air brush with a pressurized nitrogen stream. Scanning electron micrographs show the...
متن کاملSuperoleophobic cotton textiles.
Common cotton textiles are hydrophilic and oleophilic in nature. Superhydrophobic cotton textiles have the potential to be used as self-cleaning fabrics, but they typically are not super oil-repellent. Poor oil repellency may easily compromise the self-cleaning property of these fabrics. Here, we report on the preparation of superoleophobic cotton textiles based on a multilength-scale structure...
