Stainless steel (SS) has long been widely used in the outdoor environment as engineering material due to its excellent corrosion resistance. Recently it is found that super-hydrophobicity on the stainless steel surface also has significant effect on its corrosion resistance. In this work, laser surface texturing (LST) and decoration of hexadecyltrimethoxysilane (HDTMS) duplex treatment were carried out to improve the super-hydrophobicity and corrosion resistance of AISI 304 SS. Comparative appraisals of super-hydrophobicity and corrosion resistance for the related samples were conducted via wetting behavior with distilled water and electrochemical performance with simulated haze solution. The surface morphologies of ground 304 SS (G-304 SS), HDTMS + ground 304 SS (HG-304 SS), surface textured 304 SS (T-304 SS) and HDTMS + surface textured 304 SS (HT-304 SS) before and after electrochemical tests were obtained by scanning electron microscope (SEM). The results showed that micropores with different designed distances have distributed on the surfaces of 304 SS samples after LST treatment. When the micropore distance was 50 μm, this HT-304 SS exhibited a highest contact angle of 158.9°. Electrochemical experiments revealed that the HT-304 SS suggested better corrosion resistance in comparison to the G-304 SS, HG-304, and T-304 SS samples, which was mainly due to its outstanding super-hydrophobicity property.

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)-TiO 2 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), X-ray 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-TiO 2 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-TiO 2 coated meshes provided an economical and beneficial solution to treat industrial oily wastewater mixtures and environmental oil spills.

As one of the most sustainable resources, wood has been widely used in the fields of construction, decoration, flooring and furniture. However, the micron-scale porous structure of wood makes it have strong moisture absorption capacity and is susceptible to bacterial adhesion. In order to expand its utility in more applications of wood products, it is necessary to make the wood have a certain antibacterial and waterproof properties. This study demonstrates a method of using hexadecyltrimethoxysilane and nano-titanium dioxide to prepare antibacterial and waterproof coating and apply it to wood surfaces. Studies have shown that this kind of wood coated with an antibacterial waterproof coating has excellent antibacterial properties (antibacterial rate as high as 99%) and waterproof properties. In addition, this antibacterial and waterproof coating does not cause a major change in the color of the wood, and at the same time increase the tensile strength and hardness to a certain extent. The above-mentioned properties of this antibacterial and waterproof coating provide a new idea for the preparation of wood coatings.

Super-hydrophobicity inspired by natural water-repellent surfaces has received tremendous attention for surface functionalization of metallic materials in many applications. Problems of corrosion and/or contamination that happens on the surface can be partially solved as the material obtained super-hydrophobicity. Appropriate surface pattern and low surface energy are the two key factors that can realize super-hydrophobicity. In the present paper, laser surface texturing (LST) followed by decoration of Hexadecyltrimethoxysilane (HDTMS) was conducted to manipulate the super-hydrophobicity and corrosion resistance of AISI 316 stainless steel (SS) on the surface. Scanning electron microscopy (SEM) and an ultra-depth field microscope were employed to characterize the surface morphologies of the received samples before and after corrosion tests. Corrosion resistance and super-hydrophobicity for the related samples were investigated using electrochemical tests and water contact angle measurements. It was found that various surface patterns differed with intervals (250, 150, 80, and d = 5 0 μ m,) between two micro-dimples have formed on 316 SS sample surfaces after LST treatment. The surface roughness values gradually increased with the decrease of interval. The 316 SS samples obviously reduced surface energy values after HDTMS decoration. In simulated haze solution, electrochemical tests demonstrated that the 316 SS sample treated with HDTMS + LST (HT-316 SS, d = 5 0 μ m) exhibited lower corrosion and higher corrosion potential current density than the smooth 316 SS (S-316 SS), HDTMS + S -316 SS (HS-316 SS), and LST 316 SS (T-316 SS, d = 5 0 μ m) samples. As expected, the HT-316 SS ( d = 5 0 μ m) exhibited the highest water contact angle of 155.85 ∘ as compared to HS-316 SS and other HT-316 SS samples. Meanwhile, the superhydrophobic surface of HT-316 SS ( d = 5 0 μ m) exhibits super-oleophilic and self-cleaning properties.

To obtain a super hydrophobic hollow fiber membrane for using in membrane contact absorption of carbon dioxide (CO 2 ), hybrid polyvinylidene fluoride-hexadecyltrimethoxysilane (PVDF–HDTMS) membranes were fabricated via the non-solvent induced phase-inversion method with ammonia water as the non-solvent additive and dehydrofluorination reagent, and HDTMS as the hydrophobic modifier. The membranes exhibited super-hydrophobicity which was attributed to the formation of rough nanoscale microstructure and low surface free energy of the outer surface. The largest contact angle of water and diethanolamine (DEA) on the membrane outer surface attained 150°. Scanning electron microscopy images revealed that the membrane outer surfaces consisted of rough microscale hierarchical spherulitic particles with a nanoscale stereoscopic coralliform microstructure. Attenuated total reflectance–Fourier transform infrared spectroscopy of the membranes indicated that the HDTMS chains grafted in the PVDF were mainly located on the outer layer of the hollow fiber membranes. The membranes showed excellent CO 2 mass transfer flux compared to our previously fabricated membrane with 8 wt % of phosphoric acid as the non-solvent additive in the dope (PVDF-PA-8). The membrane contactor with the membrane obtained by adding 1.5 wt% of HDTMS in the dope achieved the maximum CO 2 mass transfer flux of 2.23 × 10 −3 mol/m 2 s with the inlet gas (CO 2 /N 2 = 19/81, v/v) at a flow rate of 20 mL/min and the absorbent liquid (1 mol/L DEA) at a flow rate of 50 mL/min. CO 2 mass transfer flux of this membrane decreased by 17% after 17 days of operation and then remained stable.

The CoFe 2 O 4 @reduced graphite oxide (rGO) was prepared by a one-step solvothermal reaction, and then the Ag nanoparticles were deposited on the CoFe 2 O 4 @rGO by a green mild reduction reaction to form the novel Ag-CoFe 2 O 4 @rGO filler, followed by the modification of Ag-CoFe 2 O 4 @rGO using hexadecyltrimethoxysilane to form the novel H-Ag-CoFe 2 O 4 @rGO filler. The homogeneous distribution of the Ag-CoFe 2 O 4 @rGO and H-Ag-CoFe 2 O 4 @rGO fillers in the polar PVDF plastic polymer and nonpolar SBS elastomer copolymer, respectively, to form the corresponding composites was proved by SEM. The polar crystal content of the PVDF matrix in the Ag-CoFe 2 O 4 @rGO(10 wt.%)/PVDF composite was 36.13%, while the corresponding value for pure PVDF was 29.38%. The dielectric constant at 1000 Hz of Ag-CoFe 2 O 4 @rGO(10 wt.%)/PVDF and H-Ag-CoFe 2 O 4 @rGO(10 wt.%)/SBS composites was 15.54 and 2.78, respectively, while the corresponding values for pure PVDF and pure SBS were 8.39 and 2.05, respectively. Additionally, although both pure PVDF and pure SBS were non-magnetic, the magnetization values of Ag-CoFe 2 O 4 @rGO(10 wt.%)/PVDF and H-Ag-CoFe 2 O 4 @rGO(10 wt.%)/SBS composites were 0.83 emu/g and 0.47 emu/g, respectively, at 50,000 Oe. The as-prepared Ag-CoFe 2 O 4 @rGO/PVDF and H-Ag-CoFe 2 O 4 @rGO/SBS composites should have the potential for different applications including dielectric capacitors, dielectric elastomers, sensors, EMI shielding, and so on. Graphical Preparation process of CoFe 2 O 4 @rGO and Ag-CoFe 2 O 4 @rGO hybrid filler.

A superhydrophobic and superoleophilic material-modified stainless-steel (SS) mesh filter was successfully fabricated by the deposition of hierarchical butterfly-like micro/nanostructured Co(OH)2 on the SS mesh with the unipolar pulse electrodeposition method, followed by modification with hexadecyltrimethoxysilane (HDTMS) and applied to the separation of hot and corrosive oil/water mixtures. The obtained Co(OH)2/HDTMS SS mesh filter exhibited both superhydrophobicity (water contact angle as high as 157.9°) and superoleophilicity (oil contact angle of 0°) and excellent performance for the separation of oil/water mixtures under high temperature (up to 160 °C) and corrosive and ultrasonic conditions with long-term storage and reusability. It is expected that the present fabrication process could be applied to tuning the robust and thermally stable micro/nanostructures on the porous substrates for the oil/water separation under harsh conditions.
