Therefore, the development of coatings with antibacterial properties is necessary. In this paper, fluorine-containing resins were synthesized using isophorone diisocyanate (IPDI), polyethylene glycol-1000 (PEG-1000), pentaerythritol triacrylate (PETA), and 1H,1H,2H,2H-perfluoro-1-octanol as raw materials. The fluorine-containing resin was combined with different proportions of <i>p</i>-anisaldehyde and D-(+)− 3-phenyllactic acid to prepare various UV-curable formulations. The study investigated the double-bond conversion rate during the resin curing process, the glass transition temperature, and the antibacterial and hydrophobic properties of the cured resin. The results indicate that through testing of different UV-curable hydrophobic resin formulations, the optimal comprehensive performance of the coating was achieved with a fluorine-containing hydrophobic resin mass fraction of 35%, a modified bisphenol A epoxy diacrylate (6215-100) mass fraction of 40%, a trimethylolpropane triacrylate (TMPTA) mass fraction of 10%, an tripropylene glycoldiacrylate (EM-223) mass fraction of 10%, and a photoinitiator mass fraction of 5%. Finally, by blending various types and contents of mold inhibitors with the matrix resin, UV-curable mold-resistant hydrophobic coatings were prepared and subjected to antibacterial and mold resistance tests, hydrophobic angle measurements, real-time infrared analysis, and DSC testing. In this study, the diameter of the inhibition zone of coatings containing different antibacterial agents against three types of microorganisms was measured. The results showed that the blank formulation exhibited no antibacterial activity. Among the tested antibacterial agents, <i>p</i>-anisaldehyde (with a maximum addition amount of 15 wt%) and D-(+)− 3-phenyllactic acid (with a maximum addition amount of 8 wt%) showed the best antibacterial effects; the former had better activity due to its good compatibility with the coating matrix. The antifungal activity of the coatings against <i>Aspergillus flavus</i> was much higher than their antibacterial activity against bacteria.

To minimize the loss, different attempts have been made including use of an edible coating for shelf-life enhancement. Curcumin-based edible coating, a natural compound derived from turmeric (<i>Curcuma longa</i>), has gained significant attention as it has remarkable antioxidant, antimicrobial, antifungal, and bioactive properties. Curcumin as a functional component in edible coating emphasizes its role in reducing spoilage, extending freshness, and maintaining the quality of horticulture produce. Additionally, the development of natural and nanotechnology-based curcumin coatings and their encapsulation techniques show beneficial impact on food safety and security. The nanoformulation comprising nanocurcumin with other polymers is used for extending the shelf life of horticultural fruits and vegetables. However, the use of nanomaterials in the food industry is not encouraged by the scientific community. Therefore, there is always a concern of safety issues in formulations which can be leveraged by checking its bio efficacy and cell toxicity effect.

However, biologically derived pigments to date have been formulated with VOC-emitting binders. Casein, a natural, VOC-free binder used since antiquity, represents a promising alternative, though its compatibility with biologically derived pigments has not been systematically evaluated. Bacterial pigments and protein binders are sustainable because they are derived from renewable biological sources. This study investigates a novel paint formulation combining <i>E. coli</i>–derived pigment with a casein-based binder and compares its spectral durability to two mineral-based commercial paints under varied environmental conditions. Spectral intensity analysis demonstrated that biologic paint retained color stability comparable to both commercial standards; although four statistically significant differences were observed, all were below the threshold of human visual perception.

In a previous work, a new methodology for collagen esterification using polycarboxylic acids was developed. The effects of ZnO concentration and curing temperature on photocatalytic performance were systematically evaluated using a factorial design and Minitab 18 software. The optimal conditions were obtained at a concentration of 0.5 (wt%) and a curing temperature of 30 °C. These parameters were used in the BiOI immobilization methodology. Photocatalytic activity was assessed using methylene blue photocatalytic activity indicator ink (PAII) under simulated solar radiation. Statistical analysis revealed that ZnO concentration was the most significant parameter affecting photocatalytic efficiency. However, higher concentrations (0.75 wt%) promoted nanoparticle agglomeration, reducing the availability of active sites, as evidenced by SEM analysis. Comparatively, BiOI showed lower photocatalytic performance, attributed to its lower specific surface area (6.65 m² g^-1) relative to ZnO (10–25 m² g^-1) and TiO₂ (35–65 m² g^-1). Additionally, contact angle analysis revealed that immobilization of photocatalysts significantly increased the hydrophobicity of the leather surface, with contact angles rising from 53° for untreated leather to 137° for BiOI-modified samples. These changes in surface wettability contribute to improved self-cleaning functionality. Overall, these findings validate the effectiveness of this novel succinic acid-mediated immobilization strategy for producing self-cleaning leather materials and highlight the critical role of optimizing nanoparticle concentration to maximize performance.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 3","pages":"1711 - 1720"},"PeriodicalIF":2.8,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757197","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 addition of WCO not only addresses waste disposal concerns but also offers a path toward the development of high-performance, bio-based coating materials. The effects of oil pretreatment, polyol selection and reaction parameters on resin properties are discussed in this study.

Conventional antifouling coatings exhibit poor durability and pose environmental risks due to their inherent toxicity. With increasing environmental awareness and sustainability demands, research has shifted toward eco-friendly alternatives combining durability with nontoxic mechanisms. Bioinspired antifouling strategies have emerged as a transformative solution over the past decade, particularly in microstructural surface designs that mimic of the surfaces of aquatic organisms such as shark skin, lotus leaves, and coral surfaces. This paper reviews the biochemical formation mechanisms and adverse effects of marine biofouling, systematically examines various bionic antifouling strategies inspired by aquatic organisms, advances in biomimetic microstructural fabrication and performance limitations of single-mechanism approaches in dynamic marine environments. Current challenges—such as reconciling mechanical robustness with cost-effective scalability—are critically analyzed. A key conclusion is the necessity of multifunctional synergy: combining mechanical, chemical, and biological antifouling strategies to address the limitations of individual bionic antifouling technologies. This review outlines future research directions for biomimetic microstructures, leveraging artificial intelligence to optimize structural design, establish a multifunctional collaborative platform integrating diversified biomimetic strategies, and enable on-demand fabrication of long-lasting, cost-effective antifouling coatings. It is anticipated that this work will provide valuable insights for developing efficient, durable, and environmentally sustainable marine antifouling coatings.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 3","pages":"1197 - 1216"},"PeriodicalIF":2.8,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757219","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}
