The composite shell of the microcapsules provides passive protection through enhanced hydrophobicity and chloride adsorption, while the core material isophorone diisocyanate (IPDI) offers active self-healing functionality. The wettability, particle morphology, physicochemical properties, and chloride adsorption behavior of the microcapsules were investigated. The state, mechanical properties, self-healing characteristics, and anti-corrosion performance of the construction steel coatings were systematically evaluated. Experimental results demonstrated that the microcapsules exhibited passive hydrophobicity and improved chloride adsorption performance by mitigating LDH agglomeration. These passive anti-corrosion properties provided enhanced resistance to the penetration of corrosive media in the steel coatings, delaying the onset of steel corrosion. Ultra-depth quantitative analysis provided evidence of the active self-healing performance in the microcapsule-containing coatings. Furthermore, neutral salt spray tests revealed that the microcapsules significantly improved the anti-corrosion performance of the steel coating in simulated chloride-rich humid atmospheric environments. Electrochemical tests recorded an exceptional inhibition efficiency above 97% for the coating with 15% microcapsule content, reaching a peak at 98.95% within 4 days. In summary, the microcapsules synergistically enhanced the anti-corrosion properties of construction steel coatings through combined active-passive protection mechanisms.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"213 ","pages":"Article 109960"},"PeriodicalIF":7.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145978395","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}

While epoxy coatings are widely applied, their inherent defects allow water and corrosive ions to penetrate. Graphene (G) and its derivatives, graphene oxide (GO) and reduced graphene oxide (rGO), offer barrier properties but may also promote micro-galvanic corrosion due to agglomeration. This paper critically assesses the corrosion performance, and the corresponding mechanisms of epoxy coatings modified with G, GO, and rGO based on 51 published literature sources. The role of controlling mechanisms on the corrosion resistance efficiency are examined, including optimal nanofiller loading, surface functionalization, hybrid nanofiller coatings, and filler orientation within the epoxy matrix. Two categorizations of chloride exposure durations ≤24 h and &gt;24 h on the corrosion resistance efficiency of epoxy coatings modified with G, GO, and rGO are reviewed. The inclusion of G-based nanofillers into epoxy coatings significantly enhances corrosion resistance in chloride-rich environments for both short-term (≤24 h) and long-term (&gt;24 h) studies compared to a neat epoxy coating. Compared to neat epoxy, G-based epoxy coatings demonstrate superior barrier properties, with several studies reporting protection efficiencies exceeding 99 % under both short- and long-term chloride exposure. Despite this high initial corrosion efficiency, some coatings exhibited elevated delamination index (<em>DI</em>) values, indicating potential long-term interfacial degradation. In contrast, coatings incorporating oriented or functionalized G-based fillers demonstrated significantly lower <em>DI</em> values, suggesting more stable interfacial adhesion, in turn underscoring the complex interplay between initial barrier performance and long-term durability. These improvements are primarily attributed to enhanced impermeability, suppressed electrochemical activity, and optimized nanofiller dispersion. Among the synthesis methods reviewed, in situ polymerization ensures better structural uniformity and bonding, while optimized solution mixing offers a scalable, cost-effective option. While common techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM), ultraviolet–visible spectroscopy (UV–vis), and Fourier transform infrared spectroscopy (FTIR) are used to assess G dispersion in epoxy, each presents limitations—including sample artifacts, shallow probing depth, and resolution constraints—emphasizing the value of a complementary, multiscale approach for reliable characterization.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"213 ","pages":"Article 109900"},"PeriodicalIF":7.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927722","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}

Textures with different parameters were prepared via a templating method, and surface fluorination was carried out using FAS-17 to obtain fluorinated and textured ER coating (FTEC). The synergistic effects of texture side length, spacing, height, and surface fluorination were systematically investigated. The results demonstrate that fluorination coupled with textures markedly improved the surface hydrophobicity of the coatings, with the S5-15 sample exhibiting a contact angle of 154° at a texture height of 15 μm. In terms of corrosion resistance, FTEC exhibits an impedance enhancement of two orders of magnitude compared to ER coatings produced by single-texturing and single-fluorination strategies, with the S5-15 sample reaching the highest value of 2.058 × 10¹⁰ Ω·cm². Tribological tests revealed that the coefficient of friction decreased with increasing texture spacing, achieving a minimum of 0.382 for the S10-30 sample with texture height of 5 μm. Meanwhile, the wear rate reached its lowest value of 1.916 × 10⁻⁶ cm³/N·m in the S10-30 sample with texture height of 15 μm.
