The use of modern chemical tools for this purpose is highly intriguing. In this work, three novel flame retardants (FRs) containing phosphorus and triazole units were synthesized using metal-free azide-alkyne click chemistry. The FRs were designed to have different N/P ratios. The synthesized FRs were characterized using conventional spectroscopic methods. The FRs were added at various ratios to an epoxy resin, and the obtained resins were thermally cured. The thermosets' thermal and flame retardancy properties were characterized. The thermal degradation temperatures of the FR-containing epoxy thermosets were reduced to lower temperatures, but the char yields increased compared to the neat resin. Combining the triazole units and the phosphorus-containing groups led to superior flame retardancy. The limiting oxygen index (LOI) value of the thermosets was found to be as high as 42.0 ± 0.3 %. Micro combustion calorimeter (MCC) test results of the FR-containing samples showed significant reductions in the peak heat release rate values (pHRR) compared to that of the neat epoxy resin. All the FR-containing thermosets were rated as V-0 according to the UL-94 test. Furthermore, owing to the presence of N and P, intumescent behavior was observed. The significant flame retardant action of the synthesized FRs is attributed to the formation of dense intumescent chars upon combustion and to the synergistic effect of the P- and N-containing species in the gas phase, which capture free radicals and dilute the gas phase.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"207 ","pages":"Article 109396"},"PeriodicalIF":6.5,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluorinated polyurethane (FPU) is considered a promising candidate for superhydrophobic coatings. However, most FPU-based superhydrophobic coatings exhibit limited adhesion to substrates and rely on nano-SiO₂ or nanoparticles to construct micro-nano hierarchical rough surfaces. However, it has been demonstrated that the rough surfaces created by nanoparticles reduce the effective contact area between the coating and the substrate, leading to accelerated wear of the coatings. Furthermore, to ensure the durability of superhydrophobic coatings, self-healing properties must also be considered. However, most self-healing superhydrophobic coatings developed so far require prolonged high-temperature conditions or external stimuli to restore their superhydrophobicity. Therefore, developing mechanically robust superhydrophobic coatings with self-healing capabilities remains a significant challenge. In this study, we synthesized a novel fully waterborne and self-healing FPU coating using a “two-step” polycondensation method. Even on the smoothest and hardest glass substrates, the coating retained its superhydrophobicity after 200 cycles of sandpaper abrasion, 200 cycles of tape peeling, a 6-hour water droplet test and acid-base resistance tests, outperforming most previously developed superhydrophobic coatings. Additionally, the coating exhibits excellent self-healing functionality. This allowed the coating to self-heal a 100 μm scratch and restore its superhydrophobicity within 56 min at room temperature without any external stimuli. The coating also exhibited excellent self-cleaning and delayed ice formation properties.

However, SLIPS often lose its slippery features due to the easy depletion of the impregnated lubricant oil, primarily owing to external forces such as flow-induced shear stress. In this study, a sprayable marine creature inspired surface (sMIS) was fabricated to investigate the shear-induced depletion of the infused lubricant from cavities when it was exposed to highly turbulent flows in a water channel. The porosity of the sMIS surfaces is formed to play a key role in maintaining slipperiness by effectively retaining the infused lubricant inside the cavities. The porosity of the sMIS coating was optimized by varying polystyrene concentration and relative humidity by adopting the Taguchi method. The optimized sMIS coating surface (OMIS) retained its excellent slippery properties even after exposing to harsh conditions, including high-speed centrifugal forces. It demonstrated superior slippery performance compared to the non-optimized MIS and bare polydimethylsiloxane (PDMS) surfaces.

The blanching of easel paintings is a worrying phenomenon induced by excessive humidity and porous structures, often obscuring the image beneath a white haze. The research available in the literature describing solutions to solve this problem is extremely limited. In this research, new oligoamides containing hydroxyl and/or amino groups, <em>i.e.</em>, partially fluorinated oligodiethylene succinamide-<span>l</span>-tartaramide (<strong>DSTF</strong>) and oligodiethylene succinamide (<strong>DSF</strong>), were designed to give high affinity with the polar components present in paint films through non-covalent interactions, and have reduced environmental impact compared to the previously proposed perfluoroamide (<strong>DC6G900</strong>). These innovative products represent one of the few solutions proposed for this area of application. Their syntheses were carried out <em>via</em> condensation and subsequently ring-opening reaction of the short-fluorinated epoxy compound, 3-perfluorohexyl-1,2-epoxypropane (<strong>EC6F).</strong> The short-fluorinated chain has a dual effect; it improves surface performance by lowering surface tension while simultaneously reducing environmental impact compared to the perfluoro source previously used. The performance of the two new fluorinated oligoamides (<strong>DSTF</strong>, <strong>DSF</strong>) on blanched easel paintings was investigated through a series of tests, from the macroscopic to the microscopic scale.

Among the various strategies, hydrophilic coatings incorporating metal oxides utilize the photocatalytic effects to remove organic contaminants via solar-assisted chemical degradation and water sheeting mechanisms. In this study, a polyurethane (PU)-based self-cleaning coating was fabricated by integrating Ag₃PO₄/TiO₂ (APT) nanocomposites into the PU matrix. Ag₃PO₄ was selected for its high photocatalytic activity under visible light, while TiO₂ was added to improve photostability and suppress electron-hole recombination. To enhance optical clarity and mechanical adhesion, a SiO₂ interlayer was first deposited onto glass substrates using the sol-gel method followed by dip-coating. Subsequently, the PU@APT top layer was applied via dip-coating, maintaining an immersion and withdrawal rate of 200 mm/min at a 90° dipping angle. APT nanocomposites with varying TiO₂ content—10 wt%, 30 wt%, and 50 wt%—were synthesized, yielding three formulations: APT10, APT30, and APT50. Comprehensive characterization was conducted using X-ray diffraction (XRD), Attenuated total Reflectance-Fourier transform infrared (ATR-FTIR), field emission scanning electron microscopy (FESEM), photoluminescence (PL) spectroscopy, Electrochemical impedance spectroscopy (EIS) and UV–Vis diffuse reflectance (DRS). Hydrophilicity was assessed via water contact angle (WCA) measurements, while surface roughness was evaluated using Atomic Force Microscopy (AFM). Photocatalytic performance was quantified through methylene blue (MB) dye degradation under visible light irradiation. Among the developed coatings, the SiO₂-PU@APT30 exhibited optimal performance, achieving 58 % MB degradation within 3 h, significantly outperforming the SiO₂-PU@TiO₂ and Si-PU@Ag₃PO₄, which showed only 16 % and 31 % degradation, respectively. The observed enhancement is attributed to the synergistic interaction between Ag₃PO₄ and TiO₂, facilitating improved charge separation and photocatalytic efficiency. The SiO₂-PU@APT30 coated glass achieved an impressive transmittance of 86 %. By facilitating the formation of a uniform water film instead of droplets, it effectively prevents fog accumulation, providing a significant advantage over uncoated glass. Additionally, the final coating exhibited excellent hydrophilicity, with the water contact angle (WCA) significantly reduced from approximately 63° to 27° and after 30 min of visible light exposure, completely prevents condensation and droplet formation, demonstrating superior antifogging performance compared to bare glass.
