“…This demonstrates that using FC-silane SiO 2 NPs is essential for the preparation of the superhydrophobic surface. There are many reports on the utilization of FC-silane SiO 2 NPs to produce superhydrophobic surfaces [23][24][25][26][27]. The role of TiO 2 NPs was clarified according to the SEM analysis of the FC-silane SiO 2 NPs/epoxy resin sample (Figure S4).…”

Advances in harmful organism management are highly demanding due to the toxicity of conventional coating approaches. Exploiting biomimetic superhydrophobicity could be a promising alternative on account of its cost-effectiveness and eco-friendliness. Here, we introduce a facile method to fabricate a robust superhydrophobic coating on a fabric substrate. This is achieved by sequentially spraying TiO2-epoxy resin nanocomposite material and fluorocarbon-silane modified SiO2 nanoparticles (FC-silane SiO2 NPs). The superhydrophobicity is attributed to the nanoparticles constituting a micro/nano hierarchical structure and the fluorocarbon of the modified SiO2 NPs lowering the surface energy. The epoxy resin embedded in the coating layer plays an important role in improving the robustness. The robustness of the superhydrophobic surface is demonstrated by measuring the water slide angle of surfaces that are subject to salty water at 500 rpm stirring condition for up to 13 days. This study focuses on ensuring the superhydrophobicity and robustness of the coating surface, which is preliminary work for the practical management of macrofoulers. Based on this work, we will perform practical harmful organism management in seawater as a second research subject.

“…According to the Cassie-Baxter model [180], the hydrophobic behavior of the material surface is a synergic effect of the chemical properties and the roughness of the material surface. Although silicon/fluorine materials are known as very low surface energy materials, with remarkable properties, such as weather and corrosion resistance, and refractory and oxidation stability [181], the high price of silicon/fluorine-modified coatings, and their difficult elaboration process, limits their applications. A more economical method to fabricate a formulation based on fluorine resins and SiO 2 nanoparticles yielded performance comparable to other commercially available systems.…”

Starting with a description of the meaning of sustainable coating nowadays, this review presents a selection of methods for sustainable coatings manufacture using raw materials, saving energy and costs. This selection creates an introduction for the coatings performances of intensively investigated coated alloys and their multifunctionality. There are many examples and EU recommendations to be discussed, and we especially chose to introduce sustainable coatings with both industrial and medical functions, such as bioinspired films and coatings on high-entropy alloys, biodegradable metallic alloys, etc. A special focus is on nanotechnology and nanomaterials in green procedures, enhancing coatings’ multifunctionality, introducing green corrosion inhibitors, smart additives, and coatings based on superhydrophobicity. The conclusions and future perspectives of sustainable and multifunctional coatings, as expressions of sustainable advanced materials, are based on important motivations of such studies.

“…Since fluorine atoms with strong electronegativity are strongly bonded to the carbon atoms, the chemically stable fluoroalkyl side groups limit others atoms to traverse and wedge into the Si O Si main chain, playing a "shielding effect." 11 Therefore, the fluorinated polysiloxanes exhibit excellent chemical resistance. In addition, the replacement of hydrogen atoms by fluorine atoms not only forms a strong C F bond, but also strengthens the side C C chain, which brings the fluorinated polysiloxanes with unique properties including good mechanical behavior, excellent thermal stability, low-refractive index, predominant hydrophobicity, and oleophobicity.…”

“…Due to the close atomic radii of fluorine and hydrogen atoms, the substitution of fluorine atoms for the hydrogen atoms in the side carbon chain makes the fluorinated polysiloxane a unique “pseudo effect.” Fluorine atoms just wrap the carbon chain tightly, putting a suitable “coat” on the carbon chain. Since fluorine atoms with strong electronegativity are strongly bonded to the carbon atoms, the chemically stable fluoroalkyl side groups limit others atoms to traverse and wedge into the SiOSi main chain, playing a “shielding effect.” 11 Therefore, the fluorinated polysiloxanes exhibit excellent chemical resistance. In addition, the replacement of hydrogen atoms by fluorine atoms not only forms a strong CF bond, but also strengthens the side CC chain, which brings the fluorinated polysiloxanes with unique properties including good mechanical behavior, excellent thermal stability, low‐refractive index, predominant hydrophobicity, and oleophobicity 12–14 .…”

In this study, we fabricated the multifunctional fluorophenyl polysiloxane coatings with different grafting densities of fluorophenyl groups. The structure and emulsion stability of fluorophenyl polysiloxanes were analyzed by Fourier-transform infrared (FT-IR) spectrum, nuclear magnetic resonance, particle size, and zeta potential, and the application performance of fluorophenyl polysiloxanes were investigated. FT-IR spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy proved the successful application of fluorophenyl polysiloxanes onto cotton fabrics. Afterwards, the liquid repellency, thermal stability, and deepening performance of cotton fabrics treated with fluorophenyl polysiloxane coatings were investigated. Results showed that all the treated cotton fabrics possessed contact angles greater than 110 , and cotton fabrics treated with FPPS-23 (fluorophenyl polysiloxane with 23% theoretical fluorine content) obtained the best thermal stability. Additionally, the blue cotton fabric and orange cotton fabric treated with FPPS-23 had the best deepening performance with K/S values as 27.23 and 20.56, which increased by 34.20% and 16.82%, respectively.
