Superhydrophobic films

In this communication we will address the formation of the polymer morphology leading to superhydrophobic films and how this morphology is influenced by the polymerization conditions.

Surface Energy, and Adhesion of SAMs and Superhydrophobic Films... 

An extensive review has been presented on surface forces, surface energy and stress, wetting and adhesion of SAMs, and superhydrophobic film. Relevant theoretical models, experimental results, and MD simulation results are discussed in detail. 

Emphases of this review are placed on the mechanical problems of SAMs and related surface properties. It is expected that this review will assist in understanding the mechanics of adhesion related to SAMs and superhydrophobic films. 

The electrochemical deposition approach was initially used for depositing orga-nofunctional silane sol-gel films for promoting adhesion between aluminum alloy and epoxy resin [Ij. Later, it was used for preparing silane films for corrosion protection of metals, electrochemical stripping analysis of metal ions, and microextraction of organic compounds [18,20,22,42,45]. The recent development of the electrochemical deposition of sol-gel-based composite films opens various applications such as encapsulating proteins, enzymes, and bacteria. In this section, we will show three main applications of eiectrodeposited sol-gel films, that is, corrosion protection and adhesion promotion, electrochemical sensors, and finally biocomposite films. Other applications such as solid-phase microextraction (SPME), nonlinear optics, antireflection, electrocatalysis, and superhydrophobic films are also discussed.

Figure 6(A) is an illustration of a superhydrophobic, self-assembled silica microsphere film reported by Sun et al. (2007). Figure 6(B) is a 3D atomic force microscopy image of hierarchically ordered microporous polymer formed by spontaneous assembly of water vapor condensation, so-called breath figure method (Zander et al., 2007). Tsai and Lee (2007) reported a raspberry-like structure of superhydrophobic films by assembling one...
