“…The C*F 2 and C*F 3 signals with high‐binding energies occurred at 291.7 and 293.6 eV, respectively. A weak peak at approximately 291.3 eV could be ascribed to the π–π satellite from the phenyl groups 34,35 . The Si 2p peak in Figure 6b was decomposed into two components: Si*C at 101.3 eV and SiO* at 102.8 eV.…”

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.

“…Nevertheless, some defects of polyacrylate, including poor thermal stability and UV resistance, need to be improved for further applications. Improvement in thermal stability and UV resistance of polyacrylates can be achieved by copolymerization with silicone materials [7,8], however, it is a remarkable fact that the strategies for fabrication UV-cured silicone modified polyacrylates reported by these references are somewhat complicated and the price of the products may be much expensive than pure UV-cured polyacrylates because the cost of the silicone raw materials are to some extent more expensive than acrylates. Therefore, it looks wonderful to fabrication silicone modified polyacrylates possessing the advantages of both polyacrylate and silicone material using a little few silicone raw materials with a small increase in costs.…”

UV–curable polyacrylate is widely used in free–radical type UV–cure coating systems, the disadvantages of which including poor thermal stability and UV resistance can be overcome through chemical modification by silicone. However, it is a remarkable fact that the strategies for fabrication UV–cured silicone modified polyacrylates are somewhat complicated and the price of the products may be much expensive than pure UV–cured polyacrylates. In this work, an easy fabrication method to prepare inexpensive UV–cured transparent silicone modified polyacrylate coatings with good adhesion and UV resistance performance was developed from copolymers of acylates and thiol silicone resin by UV initiated thiol–ene click reaction without UV initiator. The striking results with a high application value should be emphasized that when the amount of thiol silicone resin is only one wt.% of the copolymer of acrylates, the UV–cured coatings obtained exhibit fairly good performance. These coatings prepared exhibit transparency higher than 96% (800 nm), adhesion property to glass slides can reach grade 0, pencil hardness can reach 6H, water absorption is less than 0.16%. In particular, it is observed obviously that the silicone modified polyacrylate coatings exhibit better UV resistance performance than the coating prepared with only copolymers of acrylates initiated by UV initiator 1173. It is proved that it is actually an easy fabrication method to prepare inexpensive UV–cured transparent silicone modified polyacrylate coatings with high performance by UV initiated thiol–ene click reaction of copolymers of acylates and thiol silicone resin.

“…The results showed that when the amount of hydroxyl fluorosilicone oil was 40 wt%, compared with polyurethane, the water contact angle of fluorosulfur polyurethane (FSPU) increased to 113.6 • , the water absorption rate decreased to 0.7%, and the hydrophobic property was significantly improved. Yi Zhou et al [15] prepared hydrophobic fluorosilicone polyacrylate polyurethane coating and clarified the surface self-segregation characteristics of the fluorine segment and the silicon segment. The coating showed excellent surface hydrophobicity with amphoteric points, strong thermal stability, and controllable mechanical properties.…”

This article selects studies on the preparation of fluorinated polyurethane-nano-alumina composite coating materials, and analyzes the anti-wear, water resistantance, and surface microstructure. Attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) shows that the polyurethane synthesized in this study does not contain hydrophilic –CH2OH groups. The cavitation wear test depicts that the actual cavitation amount C of the Al2O3-FPU (4) (fluorinated polyurethane) coating is 0.9035 × 10−3 kg, and the anti-wear ability increases by 61.9% compared with FPU-0.5. The water-resistant test shows that the contact angle of water droplets on the surface of the coating increase from 95.3° of FPU-0.5 to 123.1° of Al2O3-FPU (4), and the water absorption decreases from 2.52% to 1.04%. Scanning electron microscopy (SEM) observation confirms that alumina particles can protrude on the coating surface and resist strong wear, while the C-F chain with high bond energy at the near-surface exhibits high strength and water resistance, which prevents wear from spreading deep into the coating. Differential scanning calorimetry (DSC) results show that the Tg(HS) value of the hard segment phase decreases with higher external force. Notably, when the coating is subjected to erosion, which enhances the crystallinity of the hard segment phase, the tensile strength of the hard segment phase of the coating surface is improved, which supports the wear resistance. Herein, we show that the addition of nano-alumina to fluorinated polyurethanes can control high water and abrasion resistance.
