These deficiencies lead to aging failure and degradation of protective performance. In this study, a covalent chain-segment redesign strategy is proposed by grafting three fluorinated phenyl isocyanates—4-fluorophenyl isocyanate (4FI), 4-trifluoromethoxyphenyl isocyanate (4TOPI) and 4-trifluoromethylphenyl isocyanate (4TPI) onto the hydroxyl groups (–OH) of EP to enhance backbone chemical stability and to elucidate substituent-dependent reinforcement in anticorrosion and anti-aging performance. The research revealed that all three small-molecule graft-modified coatings (EP-4FI, EP-4TOPI, EP-4TPI) exhibit superior anti-aging performance compared to blank EP coating under various aging conditions, including salt spray, UV irradiation, and chemical immersion. The overall performance ranking is EP-4TPI &gt; EP-4TOPI &gt; EP-4FI, and the impedance modulus of EP-4TPI coated on Q235 carbon steel substrate increased 1–5 orders of magnitude compared to blank EP and remained constant at 10¹⁰ Ω·cm² after undergoing all aging tests. Owing to fluorine incorporation and the concomitant reduction of hydrophilic –OH sites, the modified coatings maintain a hydrophobic surface even after aging, thereby effectively suppressing electrolyte permeation. In particular, the CF₃-substituted 4TPI structure provides enhanced resistance to UV-induced photo-oxidation and chemical corrosion. Quantum chemical calculations further suggest that fluorine-containing segments preferentially interact with corrosive species, delaying their transport toward the metal/coating interface. This work demonstrates an efficient small-molecule grafting approach to simultaneously improve corrosion protection and weathering resistance of epoxy coatings on carbon steel and provides guidance for fluorinated motif selection.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"213 ","pages":"Article 109997"},"PeriodicalIF":7.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078607","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}

Inspired by the idea of breathable coating in textile industry which allows water vapor to pass but blocks liquid water, a waterborne polyurethane (WPU) coating incorporated with custom-synthesized SiO₂ hollow nanoparticles has been developed in this work. The nanoparticles possess meso-pores on the shell and hollow structure in the middle, able to provide channels for water vapor, oxygen and chloride. Such coating allows rust deposition beneath it and acts as a temporary shelter against the external environment at the initial stage. Different coating thicknesses (10 μm to 40 μm) with different contents of SiO₂ nanoparticles (1 to 2 wt%) have been investigated on Q420 weathering steel, and the thickness of 10 μm and 2 wt% SiO₂ nanoparticles have been identified as the best option.

The objective of this study was to assess teak (<em>Tectona grandis</em>) extractive as a natural photostabilizer and compare its photostabilization performance with that of a commercial hindered amine light stabilizer (HALS) on fast-growing wood. Accelerated UV exposure experiments were conducted on four groups of Chinese fir (<em>Cunninghamia lanceolata</em>): control (C), HALS-treated (HALS), teak extractive-treated (EtE), and a combined HALS-teak extractive treatment (HEtE). The evolution of surface color, gloss, microscopic morphology, and chemical structure during UV exposure was investigated. Additionally, the chemical composition of the extractives before and after exposure was analyzed to elucidate their photostabilization mechanism. After 384 h of UV exposure, the total color difference (ΔE) of the control group reached 35.79, whereas the HALS, EtE, and HEtE groups exhibited reductions of 22.9 %, 63.1 %, and 70.7 %, respectively. The EtE and HEtE groups showed significantly reduced surface damage and lignin photodegradation. Mechanistic analysis revealed that 2-methylanthraquinone in the extractives acted as a UV absorber, while squalene contributed to free radical-scavenging activity. After UV exposure, the relative contents of these compounds decreased by 52 % and 86 %, respectively, confirming their key roles in the photostabilization process.

The strategy involves incorporating fluorinated multi-walled carbon nanotube (f-MWCNTs) into an epoxy (EP) matrix to form a hierarchical rough structure while exploiting their strong light absorption capability to impart photothermal responsiveness. The results indicate that after optimizing the filler-to-resin ratio, the coating achieved a water contact angle (WCA) of 156°, a water sliding angle (WSA) of 3.5°, and a light absorption rate of up to 97.49 %, demonstrating both excellent superhydrophobicity and high light absorption properties; at −10 °C, the icing delay time is extended by more than four times compared to the substrate, which is primarily attributed to the air layers within the rough structure effectively retarding heat transfer. At room temperature, the surface temperature increased by 30 °C within 300 s under 1.0 sun irradiation, while under −10 °C, the same irradiation achieved complete ice removal within 6 min, attributable to the exceptional photothermal conversion efficiency of MWCNTs.
