This study reports the synthesis and comprehensive characterization of a multifunctional foam featuring exceptional superhydrophobic and superoleophilic properties, tailored for advanced anti-corrosion, self-cleaning, and oil-water separation applications. Utilizing chicken eggshell waste, we developed a sustainable, fluorine/silane-free coating by first synthesizing functionalized calcium carbonate (FCC) with a cactus-like micro/nanostructure. This FCC exhibited a core-shell structure with a crystalline core and an amorphous calcium carbonate shell. We then fabricated the r-AC-FCC-coated foams using dip-coating and reduction techniques. The r-AC-FCC coating demonstrated outstanding anti-corrosion performance, particularly in saline conditions, with an inhibition efficiency surpassing 80 % and significant corrosion rate reductions in acidic and alkaline environments. The foam achieved a remarkable oil-water separation efficiency of 97 %, showcasing an impressive oil adsorption capacity of 12-65 g/g. Enhanced mechanical properties of r-AC-FCC coated foam were noted, with compressive strength and modulus of elasticity improved by 69 % and 119 %, respectively. The foam also exhibited superior self-cleaning performance and maintained high efficacy over multiple reuse cycles. Biocompatibility tests indicated effective oily wastewater treatment, significantly improving mung bean germination rates. This innovative foam leverages the optimal synergy between surface roughness and energy, underpinned by FCC's hierarchical nanostructures and robust r-AC anchoring, offering a powerful, sustainable solution for environmental remediation and material protection.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"201 ","pages":"Article 109144"},"PeriodicalIF":6.5,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419863","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}

Compared to conventional abrasive blasting, the AWT processing provided higher surface roughness and surface deformation ratio (DR), and significantly lower residual abrasives amount. Notably, the study found a tendency for adhesion to decrease with increasing surface roughness. This is in contrast to the conventional literature, which suggests that adhesion to paints and adhesives improves with increasing surface roughness up to a certain threshold level. On the other hand, DR showed a strong positive correlation with adhesion, but above a certain value, adhesion tended to be lower than that of the blast treatment. The findings indicate that it is preferable to consider both conventional surface roughness and DR concurrently when assessing adhesion.

The key aspect of this transformation is the augmentation of the antifouling capabilities of matrix resins, which enables a substantial reduction in the use of antifouling agents. Consequently, research on high-performance self-polishing antifouling matrix resins is of utmost importance. Herein, to prepare a multifunctional zinc acrylate polymer for marine antifouling, an acrylate siloxane monomer (ASM) that undergoes free-radical polymerization with acrylate monomers was synthesized by grafting a hydroxyl-containing organosilicon intermediate (RSN-6018) with hydroxyethyl methacrylate. The prepared coating demonstrates excellent transparency in the short term after the addition of the ASM, addressing the issue of the poor compatibility of the organosilicon-modified zinc acrylate polymer. After immersion in seawater for 35 d, the organosilicon-modified zinc acrylate polymer exhibits a stable hydrolysis performance, facilitating the self-polishing of the coating. Because of the presence of the siloxane structure, the coating maintains stable hydrophobicity even after soaking in seawater for 35 d, demonstrating a contact angle of 115.0° ± 1°. The organosilicon-modified zinc acrylate polymer coating has an inhibition rate of up to 99 % against <em>Staphylococcus aureus</em> and exhibits antifouling effects lasting for more than two months in the actual marine environment.

Solid aluminium begins to melt at temperatures above approximately 660 °C, which can exacerbate fire hazards by transferring significant heat from the exposed side to the unexposed side. This research investigates the fire performance of solid aluminium by incorporating two different commercially available water-based intumescent coatings (Coating-A and Coating-B) under fire conditions with high temperatures around 1000 °C. The study evaluates 0.5 mm thick solid aluminium panels with and without coatings to determine their effectiveness in mitigating fire risks. Comprehensive analyses, including SEM, XRD, TGA and fire tests, were conducted to assess the microstructure, elemental composition, thermal degradation and fire behaviour. The findings reveal that while solid aluminium without intumescent coating presents significant fire risks when exposed to high temperatures, intumescent coatings can substantially improve the fire resistance of solid aluminium. When Coating-A is applied to both sides of the solid aluminium, it reduces melting with a resistance factor of 0.70. But it still allows some flame spread. In contrast, Coating-B provides exceptional fire protection with a resistance factor of 0.86, preventing melting and flame spread when applied to one side. Between Coating-A and Coating-B, Coating B provides better fire protection, allowing only 14 % heat transfer. However, the key issue is the potential hazard of airborne char particles generated from Coating-B. These results underscore the importance of selecting effective intumescent coatings to enhance fire safety in solid aluminium cladding systems.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"201 ","pages":"Article 109142"},"PeriodicalIF":6.5,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
