From Nature To Biomimetics: Studies On The Preparation Of The Superhydrophobic Materials

Inspired by the superhydrophobic phenomena in the nature, a series of methods for the superhydrophobic surfaces preparation of different kinds of materials were developed. The detail structure investigation and the related properties of the fabricated superhydrophobic surfaces were carried out. The main contents and conclusions are listed in the following.1. The recent development of the studies on superhydrophobic phenomena which existed in the nature was reviewed. The current biomimetic preparation of the superhydrophobic surfaces, the category of the artificial superhydrophobic surfaces, the properties of the superhydrophobic surfaces, and the potential applications of the superhydrophobic surfaces were reviewed too.2. A novel preparation method of superhydrophobic surface for the steel, copper and titanium alloy was presented that the wet-chemical etching method and the surface modification were employed to fabricate biomimetic superhydrophobic surfaces on these engineering materials. The topography and the chemical composition of these surfaces were investigated in detail. The superhydrophobicity of the steel and copper alloy in the corrosive environment were also evaluated. The related theory models were employed to explain this phenomenon.3. A novel preparation method of superhydrophobic surface for the noble metal was presented that a superhydrophobic surface was achieved on Pt via the electrodeposition of Pt into the pores of anodic aluminum oxide template followed by surface fluorination. The topography and the chemical composition of the surface were investigated in detail. The preparation method is easily to be extended from platinum to other metal materials.4. A preparation method of superhydrophobic surface for the conducting polymer was demonstrated that Polyaniline was electrodeposited into the pores of anodic aluminum oxide template followed by surface fluorination. The topography and the chemical composition of the surface were investigated. The preparation method is able to be extended from Polyaniline to other conducting polymers.
