In this study, a novel melamine resin oligomer (AMFO) with trifunctional groups (-CH₂-OH, -CH=CH₂ and -O-C(CH₂)₂-CO-C₆H₅) was designed and synthesized with amidated melamine (AM) as raw material. Then the composite coating solution of AMFO,1,1,1-trimethylpropenyl-triacrylate (TMPTA) and methacrylic acid (MA) was prepared and cured quickly under sunlight to become a functional optical coating– melamine resin coating (AMFC). The results showed that the mixed coating solution composed of 1 parts TMPTA and 20 parts MA and 100 parts AMFO could be completely cured under sunlight for 30 min. The prepared AMFC exhibited a transmittance of 98.2 %, a refractive index of 1.5589, a water contact angle of 102°, a tensile strength of 8.92 MPa, an impact resistance of 110 mm, a pencil hardness of 5H, an adhesion strength of 9.09 MPa, and a combustion grade B. The AMFC demonstrated outstanding light transmittance, self-hydrophobicity, structural toughness and inherent flame retardancy, as well as antifouling, self-cleaning and chemical corrosion resistance. The inner reason is that the free radical polymerization of -CH=CH₂ induced by -O-C(CH₂)₂-CO-C₆H₅ in AMFO structure, the polycondensation of -CH₂-OH promoted by acid, and the cross-linking reaction have efficient synergistic effects. The polymerization of various active groups promoted the formation of the integrated in situ interpenetrating network (IPN) structure of AMFC. This work establishes a key foundation for melamine-formaldehyde resin (MF) applying in functional optical coating technology.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109223"},"PeriodicalIF":6.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600740","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}

The analyses revealed that polydopamine effectively covers the examined surfaces; however, its structure and uniformity depend on the substrate. On glass and polycarbonate, the coating formed a compact layer, whereas on paper, it developed a striated structure covering the cellulose fibers. Over time, a gradual decrease in nitrogen content in the surface layer was observed, suggesting polydopamine degradation, likely influenced by UV radiation. Contact angle measurements showed changes in coating hydrophilicity, which gradually returned to values characteristic of uncoated substrates over time. The reducing activity of polydopamine in silver deposition from an aqueous solution decreased by 40–60 % over time.

The current particle/polymer PDRC coatings still suffer from various shortcomings, including monotonous color, poor adhesion, limited scalability for mass production, challenges in large-scale application, and the absence of self-cleaning capabilities. These limitations make it difficult to fulfill the demands of modern energy-efficient buildings for high-performance and multi-functional architectural coatings. In this work, a primer, primarily composed of zeolite (Z), bismuth oxide (B), and polyurea, and a topcoat, primarily consisting of nano-silica (S), polyurea, and polydimethylsiloxane (PDMS), were developed. These coatings were applied to the substrate in rapid succession, resulting in the formation of a yellow self-cleaning radiation cooling (YSRC) coating after curing at room temperature for 2 h. The YSRC coating obtained exhibits a light yellow hue, with a surface contact angle (CA) of 159.1° and a sliding angle (SA) of 5.4°. It boasts a solar reflectivity of 85.6 % and an infrared emissivity of 93.9 %. When subjected to an average sunlight intensity of 481 W/m², the YSRC coating demonstrated a temperature reduction of 13.8 °C in the low-density polyethylene (LDPE) film sealed chamber and 4.5 °C in the open chamber compared to ambient temperature. Furthermore, the YSRC coating has high adhesion to the substrate, excellent resistance to UV aging and corrosion. Additionally, the building energy consumption simulation shows that the yellowish YSRC coating can achieve an annual average energy-saving efficiency of up to 11.5 % for buildings in ten typical cities across different climate zones in China, only slightly lower than the 13.6 % achieved by the white superhydrophobic radiative cooling (WSRC) coating. Therefore, the yellow YSRC coating developed in this work is of great significance for enhancing architectural aesthetics and realizing the practicality and durability of radiative cooling (RC) coatings for buildings.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109200"},"PeriodicalIF":6.5,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579373","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}

In this work, D-Tyrosine (D-Tyr) is selected to enhance rhamnolipid (RL) for evaluating their effects on corrosion caused by sulfate reducing bacteria (SRB). The results show that RL can reduce the quantity of SRB and mitigate the MIC. Lower doses of RL can achieve effective corrosion inhibition by D-Tyr enhancement.

These are usually achieved by building multistage micron/nanometer roughness or re-entrant curvature surface through low surface energy materials. However, the complexity and mechanical brittleness of amphiphobic coatings derived from surface micro/nano structures have long posed challenges to their practical application. Here, we constructed a hierarchical structure coating with amphiphobic properties using polydopamine/polyethylenimine (PDE) as a connecting layer between the 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES)-modified epoxy coating (POS-EP) and the carboxylated carbon nanotube (CNTs-COOH) modified epoxy coating (CNTs-EP) via dip-coating technology. CNTs-COOH addition reduces the porosity defects in the epoxy resin and impart hydrophilicity to the coating, demonstrating excellent underwater oleophobicity (OCA = 134.6°), thereby preventing the POS-EP coating from being eroded by oily organic substances in aqueous environments. PFDTES is employed to enhance the hydrophobicity of the epoxy resin, improving the coating's impermeability and corrosion resistance, with a water contact angle of 127.2° on its smooth surface. Surface morphology and elemental analysis confirm the seamless connection of the hydrophobic and hydrophilic layers facilitated by the PDE transition layer. Consequently, the amphiphobic coating with the hierarchical structure exhibits outstanding anti-corrosion performance. Compared to the epoxy resin coatings, the amphiphobic coating's resistance (<em>R</em>_<em>c</em>) and low-frequency modulus (|Z|_0.01Hz) are improved by 2 to 4 orders of magnitude after 60 days of immersion testing in 3.5 wt% NaCl and 18 days of neutral salt spray tests. Even the coating suffered the local damages, the synergistic effects between the amphiphobic interface can still hinder the attacks of corrosion media, and thus continues to supply good anti-corrosion properties. Given its low cost, scalability, and durability, this novel coating is expected to pave new avenues for the construction of various amphiphobic coatings.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109186"},"PeriodicalIF":6.5,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579375","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}
