Superhydrophobicity and Superhydrophilicity of Regular Nanopatterns [PDF]
Nano Letters, 2005 The hydrophilicity, hydrophobicity, and sliding behavior of water droplets on nanoasperities of controlled dimensions were investigated experimentally. We show that the "hemi-wicking" theory for hydrophilic SiO(2) samples successfully predicts the experimental advancing angles and that the same patterns, after silanization, become superhydrophobic in ...

Applied Physics Letters, 2023
Non-wetting solids have been extensively studied for about 20 years due to the spectacular mobility they provide to water drops. However, they have other noteworthy properties: For instance, such materials immersed in water entrain a plastron of air, a phenomenon exploited by many creatures to hunt or breathe underwater.

Superhydrophobic Fibrous Polymers
Polymer Reviews, 2013Superhydrophobicity coming from the appropriate structuration, morphology, and low surface energy material, is a more and more demanded property in many fields. Especially superhydrophobic fibers are interesting because of their re-entrant structure and their potential applications in apparel.

Hydrophobic and Superhydrophobic Polyphosphazenes
Journal of Adhesion Science and Technology, 2009Polyphosphazenes are a class of hybrid organic–inorganic polymers that have good solubility in classical organic solvents and are thermo-oxidatively stable. Over the years, poly(dichlorophosphazene) has been used as a macromolecular intermediate to yield a number of polymers which can be hydrophobic or superhydrophobic.

Superhydrophobic cellulose nanocomposites
Journal of Colloid and Interface Science, 2008Superhydrophobic cellulose nanocomposites were prepared using a multi-step nanoengineering process. The combination of different techniques made it possible to construct novel features at the ensuing surface, characterized by both an increase in its roughness induced by amorphous silica particles and a reduction in its energy insured by perfluoro ...

Superhydrophobic Coatings for Microdevices
Journal of Adhesion Science and Technology, 2008We have developed two simple techniques to impart superhydrophobic properties to the surfaces of microdevices. In the first approach, thin films of a fluoropolymer were spin-coated on the device surfaces followed by an oxygen plasma treatment. By varying the oxygen plasma treatment time, the water contact angles on device surface could be tuned from ...

Fabrication Of Superhydrophobic Surfaces
Journal of Adhesion Science and Technology, 2008Superhydrophobicity has recently drawn a great deal of attention from both fundamental and practical application points of view. This paper summarizes the basic principles involved in creation of superhydrophobicity and reviews the diverse methods recently developed to make superhydrophobic surfaces and coatings.

BIOMIMETIC SUPERHYDROPHOBIC SURFACES
2014Inspiration from nature has been widely used in the development of new materials and in the improvement of their properties. Superhydrophobic surfaces inspired in species present in nature with highly water repellent self-cleaning properties — such as the well-known lotus leaf — are interesting examples of the biomimetic approach for the development of

Superhydrophobic Surfaces by Electrochemical Processes
Advanced Materials, 2013AbstractThis review is an exhaustive representation of the electrochemical processes reported in the literature to produce superhydrophobic surfaces. Due to the intensive demand in the elaboration of superhydrophobic materials using low‐cost, reproducible and fast methods, the use of strategies based on electrochemical processes have exponentially ...

Hydrophobicity and superhydrophobicity are well-known bioinspired properties of several plant surfaces. This kind of wetting control can lead to many applications, e.g. self-cleaning, enhanced heat-transfer properties, friction control, anti-biofouling surfaces, etc.
