Superhydrophobic surfaces by electrochemical processes

Preparation of lotus-like hierarchical microstructures on zinc substrate and study of its wettability

The main preparation process of the superhydrophobic surface and its anti-wettability effect.

Lotus leaf-like dual-scale silver film applied as a superhydrophobic and self-cleaning substrate

The structure and the mechanism of the lotus leaf-like and petal-like surfaces.

Excellent friction-reducing performance of superhydrophobic steel surface in dry sliding

Superhydrophobic micro/nano-engineered steel surfaces with friction-reducing properties were fabricated by the combination of chemical etching and stearic acid coating.

Sticky superhydrophobic hard nanofibers from soft matter

Superhydrophobic soft and hard nanofibers with various water adhesions are obtained by electrodeposition of poly(3,4-propylenedioxythiophene) (ProDOT) derivatives containing two branched alkyl chains. In the case of the hard nanofibers, the fibers are vertically aligned to the substrate and their characteristics can be easily controlled but always with high water adhesion.

Recent advances in designing superhydrophobic surfaces

The interest in superhydrophobic surfaces has grown exponentially over recent decades. Since the lotus leaf dual hierarchical structure was discovered, researchers have investigated the foundations of self-cleaning behavior. Generally, surface micro/nanostructuring combined with low surface energy of materials leads to extreme anti-wetting properties. The great number of papers on this subject attests the efforts of scientists in mimicking nature to generate superhydrophobicity. Besides the thirst for knowledge, scientists have been driven by the many possible industrial applications of superhydrophobic materials in several fields. Many methods and techniques have been developed to fabricate superhydrophobic surfaces, and the aim of this paper is to review the recent progresses in preparing manmade superhydrophobic surfaces.
