However, it is vulnerable to environmental degradation, particularly from ultraviolet (UV) radiation, which causes photochemical deterioration over time. This study evaluates oil-in-water microemulsions based on silicone oil and zinc oxide nanoparticles (ZnO-NPs) as an environmentally friendly treatment for protecting wood surfaces against UV-induced photodegradation. White poplar specimens were coated with silicone oil emulsions containing 0.1 and 0.5 wt% ZnO-NPs and subsequently subjected to 500 h of accelerated UV aging. Microscopic observations revealed a uniform distribution of nanoparticles within the coating and the formation of a stable oil layer without aggregation. Colorimetric measurements revealed that while silicone oil alone moderately reduced surface color changes, the incorporation of ZnO-NPs significantly minimized total color changes (Δ<i>E</i>*). These findings were confirmed by Fourier transform infrared (FTIR) spectroscopy, which indicated reduced lignin degradation and lower carbonyl group formation on treated surfaces compared to untreated controls. Furthermore, microemulsions with higher ZnO content (0.5 wt%) not only effectively increased the water contact angle compared to pure silicone oil, but also maintained the hydrophobicity of the surface after UV aging. This novel coating also reduced the water uptake in the treated wood, indicating the effectiveness of protecting the wood against moisture-induced damage.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 5","pages":"2487 - 2495"},"PeriodicalIF":3.4,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837694","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}

In this study, the influence of reduced and magnesium-functionalized single-layer graphene oxide (rfGO) on the structural and electrochemical behavior of nano-hydroxyapatite (nHA)/chitosan (CS)/gelatin composite coatings deposited on 316L stainless steel via electrophoretic deposition (EPD) was systematically investigated. The coatings, containing varying rfGO contents (0, 0.3, 0.5, and 0.7 mg per 10 g HA), were fabricated under different EPD voltages. The nHA was synthesized by a sol–gel method, while graphene oxide was reduced and subsequently functionalized with Mg. The powders and coatings were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), and dynamic light scattering (DLS) analyses. Electrochemical performance was assessed through polarization and impedance. FTIR confirmed the successful formation of rfGO, and microstructural analyses demonstrated uniform deposition of HA/CS/gelatin/rfGO coatings. Increasing the EPD voltage promoted crack formation; however, incorporation of rfGO significantly improved coating integrity and reduced cracking, with higher rfGO contents yielding crack-free coatings even at elevated voltages. The coating thickness increased by 41% at 0.7rfGO (4.8 µm) relative to rfGO-free coating (3.4 µm). Coating mass ranged from 2.1 mg (0rfGO-80 V) to 8.1 mg (0.7rfGO-120 V). Electrochemical studies revealed that rfGO generally enhanced corrosion resistance from 165 to 177 Ω cm², except at the highest loading (0.7rfGO), which showed inferior performance (147Ω cm²) compared to both the uncoated substrate and rfGO-free coatings. The optimal corrosion resistance was achieved for the 0.5rfGO-100 V coating, with a polarization resistance of 385 Ω·cm². Equivalent circuit modeling of EIS data further elucidated the corrosion mechanisms governing coating behavior.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 5","pages":"2717 - 2740"},"PeriodicalIF":3.4,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837695","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}

Biofouling, the accumulation of aquatic organisms on submerged surfaces, presents significant economic and ecological challenges, including increased fuel consumption, structural degradation, and the spread of invasive species. The phase-out of toxic organotin-based antifouling paints, particularly tributyltin (TBT)-based formulations, has driven the search for safer and more effective alternatives. This review provides an in-depth analysis of the historical evolution of antifouling coatings, the impact of biofouling across various industries such as heat exchangers, jetties, offshore rigs, shipping vessels, and aquaculture cages, and the limitations of existing antifouling coatings. It highlights the role of interdisciplinary research in advancing antifouling strategies and explores emerging materials such as conducting polymers, hydrogel coatings, and bio-based formulations for antifouling and anticorrosion applications. The review underscores the potential of these innovative materials while emphasizing the need for further research to enhance their long-term effectiveness and environmental compatibility. Additionally, the current review paper covers various antifouling strategies, including biocide-based coatings, fouling-release coatings, and nonfouling coatings, which have been developed to prevent marine growth. The transition from traditional copper-based coatings to sustainable alternatives, such as silicone-based fouling-release coatings and biomimetic materials, reflects the growing regulatory and environmental concerns surrounding conventional antifouling technologies. Advancements in biomimetic, enzyme-based, and nontoxic polymer coatings are further explored, demonstrating their potential to provide durable, eco-friendly antifouling coatings. To illustrate the practical implications of biofouling and mitigation strategies, the discussion highlights the economic and operational challenges posed by biofouling and evaluates the effectiveness of antifouling interventions. The review concludes with key findings, industry implications, and future research directions, advocating for continued innovation in sustainable and efficient antifouling technologies to address the evolving demands of the maritime and naval industries.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 3","pages":"1291 - 1334"},"PeriodicalIF":2.8,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757179","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}

Despite the development of various coatings, those capable of preventing microbiologically influenced corrosion (MIC) in metals remain limited. In this research, we have developed a novel type of coating that combines superhydrophobic and antibacterial characteristics, suppressing biofilm formation and preventing corrosion. Two antibacterial superamphiphobic coatings, termed as FPPDC and FPPTC, were created by synthesizing antibacterial fluorinated silica particles through a sol–gel process and incorporating them with two quaternary ammonium salts, i.e., DMOAP and TMAPS, respectively. The FPPDC coating outperforms the FPPTC counterpart in antibacterial performance, mechanical durability, and corrosion resistance. The FPPDC coating achieves a bactericidal efficiency of 99.99% against sulfate-reducing bacteria, higher than 99.00% for the FPPTC coating. Additionally, the FPPDC coating maintains its superhydrophobicity after 1200 abrasion cycles, while the FPPTC loses this property after 1000 cycles. The FPPDC coating successfully combines fluorinated chains and quaternary ammonium salts to achieve both antibacterial and anticorrosion functions, with excellent mechanical stability, making it suitable for MIC mitigation in oilfield environments.

However, poor reproducibility of the biological route of synthesis is a matter of concern. M and MO nanoparticles find extensive application in marine antifouling coatings, exterior paint coatings, antimicrobial protective coatings for surfaces in clinical settings and hospital environments, and antimicrobial textiles.

Methods for surface immobilization of M and MO nanoparticles to develop an antimicrobial surface were actively researched during the last two decades; however, recently M and MO nanoparticles have found increasing application in combination with polymer matrix to form antimicrobial polymer nanocomposites. This advantage is due to the new generation of antifouling coatings, known as nanocomposite polymer coatings, having a chemical composition free of toxins and being simple to apply on a large scale.
