TLDR
Research on superhydrophobic materials has mostly focused on their extreme non-wettability, but the implications of superHydrophobicity beyond wetting, particularly for transport phenomena, remain largely unexplored.Abstract:

Recent Developments and Practical Feasibility of Polymer-Based Antifouling Coatings
TL;DR: In this article, the authors highlight the novel and exciting antifouling techniques while simultaneously assessing their performance and practical feasibility, and highlight some of the most promising antifoul-resistant, release and degradation-degrading coatings.
Journal ArticleDOI
Drag reduction using lubricant-impregnated surfaces in viscous laminar flow.
TL;DR: The potential for LIS to reduce drag in laminar flows is demonstrated and the dependence of drag reduction on the ratio of the viscosity of the working fluid to that of the lubricant is elucidated.

Oleoplaning droplets on lubricated surfaces
Dan Daniel,Jaakko V. I. Timonen,Jaakko V. I. Timonen,Ruoping Li,Seneca J. Velling,Joanna Aizenberg,Joanna Aizenberg +6 more
TL;DR: In this paper, the authors show that for a moving droplet, the film thickness follows the Landau-Levich-Derjaguin law and the droplet is therefore oleoplaning with minimal dissipative force and no contact line pinning.
Journal ArticleDOI
Water and Blood Repellent Flexible Tubes
TL;DR: A top-down scalable method to produce flexible water and blood repellent tubes is introduced based on replication of overhanging nanostructures from an aluminum tube template to polydimethylsiloxane (PDMS) via atomic layer deposition (ALD) assisted sacrificial etching.
Journal ArticleDOI
Self-similarity of contact line depinning from textured surfaces
Adam T. Paxson,Kripa K. Varanasi +1 more
TL;DR: In this paper, the authors examined a superhydrophobic surface on which a drop's adhesion is governed by capillary bridges at the receding contact line and showed that the Gibbs criterion is satisfied at the micro-scale.

Wetting: statics and dynamics
TL;DR: In this paper, the authors present an attempt towards a unified picture with special emphasis on certain features of "dry spreading": (a) the final state of a spreading droplet need not be a monomolecular film; (b) the spreading drop is surrounded by a precursor film, where most of the available free energy is spent; and (c) polymer melts may slip on the solid and belong to a separate dynamical class, conceptually related to the spreading of superfluids.

Designing Superoleophobic Surfaces
Anish Tuteja,Wonjae Choi,Minglin Ma,Joseph M. Mabry,Sarah A. Mazzella,Gregory C. Rutledge,Gareth H. McKinley,Robert E. Cohen +7 more
TL;DR: It is shown how a third factor, re-entrant surface curvature, in conjunction with chemical composition and roughened texture, can be used to design surfaces that display extreme resistance to wetting from a number of liquids with low surface tension, including alkanes such as decane and octane.
Journal ArticleDOI
Wetting and Spreading
TL;DR: In this article, the surface forces that lead to wetting are considered, and the equilibrium surface coverage of a substrate in contact with a drop of liquid is examined, while the hydrodynamics of both wetting and dewetting is influenced by the presence of the three-phase contact line separating "wet" regions from those that are either dry or covered by a microscopic film.
Journal ArticleDOI
Characterization and Distribution of Water-repellent, Self-cleaning Plant Surfaces
TL;DR: The importance of roughness and water-repellency, respectively, as the basis of an anti-adhesive, self-cleaning surface, in comparison to other functions of microstructures, is discussed.
Journal ArticleDOI
Progess in superhydrophobic surface development.
TL;DR: The origins of water-repellent surfaces are discussed, examining how size and shape of surface features are used to control surface characteristics, in particular how techniques have progressed to form multi-scaled roughness to mimic the lotus leaf effect.
