In this study, a multi-technique approach was used to investigate molecular interactions at the coating–steel interface.

Complementary attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR) showed accumulation of unreacted epoxide groups, reduced β-hydroxyl formation, and suppressed epoxy–amine curing, together revealing an interphase with a significant degree of covalent Fe–O–C bonds.

This study investigates partially acrylated tannic acid derivatives (TA–GMx) as bio-based adhesion promoters for EB-curable acrylic coatings in metal packaging applications. Tannic acid was functionalized with glycidyl methacrylate to tailor its polarity and introduce polymerizable groups capable of directly participating in EB-induced crosslinking. The resulting TA–GMx additives, synthesized with varying degrees of acrylation x, were incorporated into an industrial, partially bio-based formulation at different loadings (1.0 and 3.0 wt%). Their influence on network formation and interfacial performance was systematically evaluated. Mechanical and electrochemical tests on various metal substrates demonstrated that the incorporation of TA–GMx additives significantly improved adhesion, flexibility under deformation, and resistance to corrosion-induced delamination. Optimal performance was achieved at 1.0 wt% additive concentrations, where a balance between crosslink density and interfacial interactions was established.

PSH particles and PCs’ films were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and micro-fiber optic spectrometer. The effects of the key parameters on the formation of 2D PCs’ films and 2D anticounterfeit PCs’ films were investigated. The results showed that the amount of St could be used to regulate the particle size of PSH microspheres, thereby adjusting the structural color of PCs. As the volume ratio of water to ethanol in the range of 10:1–1:3, corresponding to the surface tension of the mixed solvents between 48.3 and 25.1 mN/m, 2D PSH PCs’ films with angular dependence could be formed on the surface by gas-liquid interfacial self-assembly. 2D PSH PCs’ films prepared at a volume ratio of 1:1 (surface tension of 28.8 mN/m) showed the strongest reflection intensity. PSH/PHEMA PCs’ composite films were successfully obtained through in-situ photopolymerization of HEMA. As the voids of 2D PCs were filled up with the monomer HEMA, the bright structural color of PCs disappeared. The composite films were colorless and transparent due to almost no refractive index difference between PSH and PHEMA. When the PSH/PHEMA PCs’ film absorbed water, the color appeared because the refractive index of water/PHEMA was lower than that of PSH. The adsorption of water further made PHEMA swollen, which enlarged the lattice spacing in 2D PCs and resulted in a red-shift of the reflected light. The patterned PSH/PHEMA PCs’ films exhibited a reversible switch between transparency and iridescent colors in dry and wet states, and would be applied in the field of anti-counterfeiting.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 5","pages":"2763 - 2774"},"PeriodicalIF":3.4,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of hydroxyalkyl acrylate on dispersion stability, UV-curing behavior, and final coating performance was systematically investigated. FTIR confirmed complete NCO consumption and the successful incorporation of acrylate groups. The choice of end-capper significantly influenced particle size, storage stability, and crosslinking density of WPUAs. HEA provided good flexibility, while HEMA increased hardness due to its higher glass transition temperature. Incorporation of multifunctional PETA markedly enhanced crosslinking density, tensile strength, and chemical resistance, but excessive PETA led to embrittlement and reduced toughness. Importantly, the WPUA prepared with HEMA/PETA at a 1:1 molar ratio exhibited the most well-balanced performance, combining long thermal storage stability (&gt;30d), high tensile strength (26.1 MPa), elevated Young’s modulus (379.3 MPa), increased pencil hardness (2H), excellent adhesion (5B), good flexibility (1 mm), and exceptional ethanol scrub resistance (1559 cycles).

In this study, an organic-inorganic hybrid nanoflame retardant (HP@ZIF) was designed and synergistically applied with ammonium polyphosphate/triazine charring agent (APP/CFA) into an epoxy resin (EP) matrix, fabricating a high-performance IFRC.

These surfaces derive their unique characteristics from hierarchical micro- and nanoscale textures combined with low-surface-energy chemistries. Advances in fabrication routes, characterization tools, and surface functionalization strategies have supported the transition of superhydrophobic coatings from laboratory prototypes to robust solutions for diverse engineering sectors. This review examines the fundamental wetting mechanisms governing superhydrophobicity and discusses emerging fabrication techniques and characterization approaches that enable precise control of surface properties. Major engineering applications are presented, including anti-icing and drag-reduction coatings in aerospace, corrosion-resistant and fouling-resistant surfaces in marine environments, and self-cleaning, antimicrobial, and low-adhesion coatings in biomedical devices, food processing equipment, and architectural materials. In addition to these widely explored domains, the review also outlines other relevant surface-related applications that broaden the technological scope of superhydrophobic coatings across industrial and functional systems. The potential of superhydrophobic materials in smart textiles, microfluidics, and environmental remediation is also highlighted. Key challenges, such as long-term mechanical durability, large-area scalability, and environmental sustainability, are discussed along with emerging trends including fluorine-free coatings, bio-inspired architectures, and multifunctional hybrid materials.
