“…Generally, the hydrophobicity of a surface can be achieved by both surface roughing and lowering surface energy [20,21]. Various methods such as chemical etching [22], electro-spinning [23], chemical vapor deposition (CVD) [24], sol-gel process [25,26] and layer-by-layer assembly [27,28] have been used to prepare hierarchical hydrophobic surfaces on Mg alloys. However, some approaches may pollute the environment because of the use of strong acid [12] and cerium nitrate [29].…”

The corrosion resistance of magnesium alloys can be improved using functional surface modification such as hydrophobic treatment. In this study, a hierarchical hydroxide zinc carbonate (HZC) film was fabricated on AZ31 magnesium alloy via a simple chemical-bath deposition process using urea aqueous solution. The morphologies, compositions and corrosion resistance of the hydrophobic film were analyzed using scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectrometer, and electrochemical measurements as well. The results revealed that the HZC film displayed flower-like protrusions and had a thickness of approximately 100 lm. The fluoroalkylsilane (FAS)-modified HZC film exhibited a hydrophobic property with a water contact angle of 131.3°. The FAS/HZC film significantly improved the corrosion resistance of the AZ31 alloy due to hierarchical structures and hydrophobic modification.

“…The low surface energy materials applicable to this purpose are alkyl amines, silicates, organic silanes, and fluorinated silanes [ 6 , 7 , 8 , 9 ]. The treatment methods used for this purpose are electrospinning, plasma treatment, chemical vapor deposition, layer-by-layer deposition, polymerization reactions, colloidal template techniques, wet chemical reactions, self-assembly, and sol-gel [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. The second component is fabrication of the photodegradable surfaces using photocatalysts, such as anatase TiO 2 [ 22 ].…”

In this study, self-cleaning polyester (PET) fabrics were prepared using TiOF2 and hexadecyltrimethoxysilane(HDS) treatment. TiOF2 was synthesized via direct fluorination of a precursor TiO2 at various reaction temperatures. The prepared PET fabrics had superior photocatalytic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics under UV and sunlight with 98% decomposition of methylene blue. TiOF2/HDS-treated PET fabrics also had superior superhydrophobic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics with a 161° water contact angle and 6° roll-off angle. After the self-cleaning tests of the non-dyed TiOF2/HDS-treated PET fabrics, we prepared dyed TiOF2/HDS-treated PET fabrics to test practical aspects of the treatment method. These PET fabrics were barely stained by tomato ketchup; even when stained, they could be self-cleaned within 4 h. These results suggest that practical self-cleaning PET fabrics with superhydrophobicity and photocatalytic degradation could be prepared using TiOF2/HDS-treatment.

treatment to create a low surface energy. [9][10][11][12][13][14] However, these biomimetic structures still vary considerably from those found in nature. To some extent, this limits the further development of super-hydrophobic materials. Nevertheless, morph-genetic materials present a novel preparation method for materials using biological structures as templates and modifying their chemical compositions to obtain new materials with structural similarities to the original biological substrate. Thus, natural templates can impart their properties onto the synthetic materials. Researchers have begun to use this method to develop super-hydrophobic materials, such as Cu, ZnO, and Si biomorphic materials, which were prepared using lotus leaves or wood as templates. [15][16][17] Zinc is an industrially important nonferrous metal, with excellent properties such as ductility, wear resistance, and casting. In particular, zinc and its alloys display excellent resistance to corrosion because a layer of dense oxide film forms on their surfaces. Therefore, zinc is often galvanized onto other materials as an anticorrosion coating, and is widely used in the automobile, shipbuilding, construction, and other light industries. However, zinc coatings adhere to acidic solutions and are easily corroded in humid and acidic environments. They are also easily stained by water under damp working conditions, which can negatively impact the appearance of the products. A variety of environments can result in corrosion to some extent, but water often plays an essential role, necessitating the fabrication of super-hydrophobic zinc surfaces. This technology will advance the field toward the goal of achieving super-hydrophobic zinc coatings, which prevent moisture absorption and corrosion and address the issues presented above.The indicalamus leaf is naturally super-hydrophobic due to its hierarchical surface structure, which is shown in Figure 1. Water droplets formed spheres with a contact angle of 151° on the surface of the leaf, as shown in Figure 1a. We found that its microstructure consists of many linear arrangements of micrometer-scale mastoids in 1D grooves on the leaf surface, as shown in Figure 1b. The diameters of these mastoids are 3-6 µm, as shown in Figure 1c. Moreover, there are numerous nanoscale flower-like slices on each mastoid, as can be seen in Figure 1d, with thicknesses of 70-100 nm. This hierarchical structure imparts hydrophobicity to the indicalamus leaf. Inspired by the concept of morph-genetic materials, we have Inspired by the idea of deriving morph-genetic materials from natural templates, the indicalamus leaf is used as a template in an electroplating method designed to prepare a zinc surface with a hierarchical microstructure similar to that of the indicalamus leaf. The leaf templates are first sintered at high temperature under vacuum to leave the carbon skeleton of indicalamus leaf behind; a layer of zinc is then plated directly onto this surface. The zinc coating inherits both the nanoscale slice structures a...
