Three-tier rough superhydrophobic surfaces

Nanotechnology, 2015
A three-tier rough superhydrophobic surface was fabricated by growing hydrophobic modified (fluorinated silane) zinc oxide (ZnO)/copper oxide (CuO) hetero-hierarchical structures on silicon (Si) micro-pillar arrays. Compared with the other three control samples with a less rough tier, the three-tier surface exhibits the best water repellency with the ...

Long-lived superhydrophobic colorful surfaces

Chemical Communications, 2013
Rough structures created from bulk materials at the surface could have superior durability. Superhydrophobic colorful surfaces were fabricated through chemical etching of the fiber surfaces, followed by diffusion of fluoroalkylsilane into fibers. The obtained superhydrophobic textiles show strong durability against severe abrasion, long-time laundering,

Electrically Tunable Superhydrophobic Nanostructured Surfaces

ASME 4th International Conference on Nanochannels, Microchannels, and Minichannels, Parts A and B, 2005
In this work, we discuss dynamic electrical control of the wetting behavior of liquids on nanostructured surfaces spanning the entire possible range from superhydrophobic behavior to nearly complete wetting. It is demonstrated that a droplet of liquid can be reversibly switched between the superhydrophobic “rolling ball” state and the hydrophilic ...

Progess in superhydrophobic surface development

Soft Matter, 2008
Research into extreme water-repellent surfaces began many decades ago, although it was only relatively recently that the term superhydrophobicity appeared in literature. Here we review the work on the preparation of superhydrophobic surfaces, with focus on the different techniques used and how they have developed over the years, with particular focus ...

Micromachined superhydrophobic surfaces

2014
Superhydrophobic surfaces have attracted a lot of attention since the potential applications of self-cleaning effect in self-cleaning textiles, fluid transport in micro/nanofluidics, bio-MEMS and so on. Different techniques have been developed to fabricate superhydrophobic surfaces with roughness in micro or nano scale.

Superhydrophobicity for Antifouling Microfluidic Surfaces

2012
Fouling of surfaces is often problematic in microfluidic devices, particularly when using protein or -enzymatic solutions. Various coating methods have been investigated to reduce the tendency for protein molecules to adsorb, mostly relying on hydrophobic surface chemistry or the antifouling ability of -polyethylene glycol.

Green Superhydrophobic Surfaces

This project aims to develop novel fluorine-free superhydrophobic (water-repelling) sur-faces, made from readily available non-toxic and economical branched low surface energy materials (LSEMs). These have important advantages over the existing LSEMs, including biodegradability, environmental acceptance and are cheaper to mass produce compared with ...
