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:

Transparent and abrasion-resistant superhydrophobic coating with robust self-cleaning function in either air or oil
TL;DR: In this article, a transparent super-hydrophobic coating which shows a robust resistance to oil contamination, knife-scratch, sandpaper abrasion and strong acid/base attack is presented.
Journal ArticleDOI
Physics and technological aspects of nanofluidics
Lydéric Bocquet,Patrick Tabeling +1 more
TL;DR: Today, in view of the markets that are targeted, nanofluidics may well impact the industry more than microfluidics; this would represent an unexpected paradox.
Journal ArticleDOI
Enhancing droplet deposition through in-situ precipitation
TL;DR: A physical model is developed to estimate the energy dissipation by the defects and predict the transition from bouncing to sticking and macroscopic enhancements in spray retention and surface coverage for natural and synthetic non-wetting surfaces are demonstrated.
Journal ArticleDOI
Thermal Processing of Silicones for Green, Scalable, and Healable Superhydrophobic Coatings.
TL;DR: The thermal degradation of silicones is exploited and engineered to make super-hydrophobic coatings that are scalable, healable, and ecofriendly for various outdoor applications.

Surface Wettability of Macroporous Anodized Aluminum Oxide
Josephus Gerardus Buijnsters,Rui Zhong,Natalia Tsyntsaru,Natalia Tsyntsaru,Jean-Pierre Celis +4 more
TL;DR: Practical guidelines for the synthesis of rough, highly porous AAO structures with controlled wettability are provided and the possibility of forming superhydrophobic surfaces is evaluated.

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.
