“…6. The absorption peaks of 2880 cm -1 , 2925 cm -1 and 1460 cm -1 corresponded to the symmetric and the asymmetric stretching vibrations of -CH3 and -CH2 groups, respectively [57,58], which indicated the presence of long chain alkyl hydrophobic mesh surface caused by HDTMS soles [53]. The peak at 1100 cm -1 attributed to the asymmetric stretching vibration of the Si-O species [57].…”

Superhydrophobic and superoleophilic meshes have attracted great attention in oil/water separating application. However, superhydrophobic surfaces are not only complicated in preparation but also easy to break in practical applications. In this paper, we prepared fluorine-free hydrophobic hexadecyltrimethoxysilane (HDTMS)-TiO2 coated meshes with properties of cost-effectiveness, easy to manufacture, and high separation efficiency by a liquid phase deposition method. The surface topography, composition, and functional groups of the meshes were characterized by field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscopy (EDS), Xray photoelectron spectroscopy (XPS), and Fourier transform microscopic infrared spectrometer (FT-IR) spectrum, respectively. A new gravity-driven oil/water separator was designed for the separation experiments. The separation efficiency of the hydrophobic HDTMS-TiO2 coated meshes maintained over 97.8% after 35 separating cycles. This study indicated that the superhydrophobicity of the separating mesh was nonessential for the highly efficient oil-water separation. The fluorine-free hydrophobic HDTMS-TiO2 coated meshes provided an economical and beneficial solution to treat 2 industrial oily wastewater mixtures and environmental oil spills.

Electrodeposition of paramagnetic copper (Cu) from a sulfate solution was investigated under magnetic fields and two different current densities. Static magnetic fields have been used during electrodeposition of paramagnetic Cu onto paramagnetic aluminum (Al) substrate to enhance the deposition rate and to alter crystallographic orientation and morphology of the film. The magnetic field might be attributed to the field-induced convection that disrupts the depletion layer near the electrode and that might also be correlated to Cu, Al, and oxygen dissolved in the solution as paramagnetic materials. An X-ray diffractometry, a scanning electron microscope with energy dispersive spectrometry, a potentiostat, and a digital camera were used for characterizing the crystal structure, morphology, the electrochemical behavior, and wettability, respectively. The results show that, at the current density of 10 mA cm −2 , raising the magnetic field from 800 to 1400 G increases the cathode current efficiency and alters the electrochemical behavior, the crystal growth, and the crystallite size. At the current density of 30 mA cm −2 , the magnetic field alters the growth and crystallographic orientation. The static magnetic field exposed during electrodeposition of Cu onto the Al alloy can control the film properties, especially crystallographic orientation and the oxygen content.

“…Hierarchical micro-/nanostructured materials with various shapes and properties are widely used in different applications like as optical materials [1], low adhesive surfaces [2], abrasion-resistant surfaces, anti-icing films [3][4][5][6], anticorrosion coatings [7][8][9], and in the fabrication of superhydrophobic surfaces [10,11]. The superhydrophobicity phenomenon was first observed in lotus leaves in nature [12,13], and it is frequently used to describe surface properties with a water contact angle (CA) larger than 150 • and sliding angle less than 10 • [14,15].…”

“…Numerous methods, including electrodeposition [7,10], chemical-vapor deposition [19], etching [20], electrospinning [21], and sol-gel [1] have been used so far for the fabrication of nickel films that are decorated with micro-/nanostructures. In this regard, electrodeposition is very attractive in comparison with other methods due to its simplicity, ease of control, minimal required material preparation, and relatively cheap equipment [9]. In the electrodeposition process, metal ions from anodes preferably nucleate and grow on the lattice defects of cathode surface [18,22] where the screw-dislocation-driven growth mechanism is dominant for 2D and 3D growth during electrocrystallization [23,24].…”

In the present study, the impact of copper substrate grain size on the structure of the succeeding electrodeposited nickel film and its consequent corrosion resistance in 3.5% NaCl medium were evaluated before and after functionalization with stearic acid. Nickel layers were electrodeposited on two different copper sheets with average grain size of 12 and 25 µm, followed by deposition of stearic acid film through self-assembly. X-ray diffraction analysis of the electrodeposited nickel films revealed that the deposition of nickel film on the Cu substrate with small (12 µm) and large (25 µm) grains is predominantly governed by growth in the (220) and (111) planes, respectively. Both electrodeposited films initially exhibited a hydrophilic nature, with water-contact angles of 56° and <10°, respectively. After functionalization with stearic acid, superhydrophobic films with contact angles of ~150° were obtained on both samples. In a 3.5% NaCl medium, the corrosion resistance of the nickel layer electrodeposited on the copper substrate with 25 µm grains was three times greater than that deposited on the copper substrate with 12 µm grains. After functionalization, the corrosion resistance of both films was greatly improved in both short and long immersion times in 3.5% NaCl medium.
