In this context, the current study focuses on the preparation of multicomponent coatings composed of tannic acid (TA)-loaded zein particles and copper-doped bioactive glasses (CuBG) embedded within a polysaccharide matrix of sodium carboxymethyl cellulose (CMC) on titanium. A novel in-situ process of combined anti-solvent precipitation and electrophoretic deposition (EPD) was exploited to simultaneously synthesize and deposit the drug-loaded zein particles together with the bioactive agent (CuBG) and the polymeric coating matrix (CMC). Compared to the conventional methods to produce coatings containing drug-loaded polymer particles by multi-step EPD, the proposed approach offers time efficiency, versatility, and controlled drug release rates. The results showed that the encapsulation of the phytotherapeutic drug in the zein particles leads to a sustained drug release from the coatings, while CuBG induces a bioactive response in the physiological environment. Furthermore, the combination of tannic acid-loaded zein particles and CuBG in the CMC-based coatings results in high cytocompatibility with pre-osteoblast MC3T3-E1 cells and a synergistic antibacterial activity against <em>S. aureus</em> and <em>E. coli</em>. The obtained outcomes suggest that the produced coatings can potentially enhance bone tissue integration and prevent infections around orthopedic implants.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"210 ","pages":"Article 109641"},"PeriodicalIF":7.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047174","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}

However, its intractable solubility and poor processability resulting from robust intermolecular hydrogen bonding and high crystallinity have long impeded the development and application of high-performance, environmentally friendly biomass coatings. To address this challenge, we propose a novel “hydrogen-bond network reconstruction” strategy. Through physicochemical co-modification disrupting chitin's microstructure, we successfully overcame its solubility barrier. Using this highly soluble chitin as the matrix and integrating flexible polydimethylsiloxane (PDMS) with hexamethylene diisocyanate trimer (HDIT) crosslinking technology, we fabricated an omniphobic coating with exceptional comprehensive properties. This coating exhibits an ultra-low surface energy (17 mJ·m⁻², lower than PTFE) and a densely cross-linked network, demonstrating not only superhydrophobicity/superoleophobicity with high contact angles (water: 110.7 ± 0.8°, diiodomethane: 80.9 ± 1.9°), excellent self-cleaning capability, and efficient anti-fouling/anti-graffiti properties, but also, owing to its reinforced network structure, remarkable mechanical stability (6H pencil hardness, A1-grade adhesion, abrasion resistance) and chemical resistance (tolerance to chemical agents, no corrosion after 10-day saline immersion, 20-fold reduction in corrosion current density (<em>I</em>_corr) compared to bare iron). Simultaneously, it maintains high optical transparency (95 %). This coating provides a green, durable, and easy-to-maintain protective solution for precision devices such as electronic displays and solar panels, significantly extending service life while reducing cleaning energy consumption.

Recent cost reduction of GNPs makes it an attractive coating filler option. However, due to their tendency to cluster, dispersing GNPs in a coating resin for practical applications remains a challenge. Herein, we report the effects of three practically used industrial dispersion methods on GNP dispersion profiles and the consequent properties of GNP-epoxy nanocomposite coatings. We studied two GNP loading levels: 0.3 wt% and 0.5 wt%, each dispersed with three different methods: high-speed disk dispersing (HSD), low-speed medium milling (LSM), and ultrasonication (USN). Optical microscopy and single particle optical sensing (SPOS) were used to obtain dispersion profiles by measuring parameters such as GNP particle/cluster size, size distribution (D10, D50, D90), and particle/cluster shape (circularity). At lower loading (0.3 wt%), coatings with GNPs dispersed by LSM showed enhanced toughness (4332.3 J/m³), elongation at break (205.1 %), and tensile strength (24.0 MPa) attributed to the breakdown of large clusters (D90 = 6.1 μm), which likely improves stress transfer within the coating matrix. The HSD method produced smaller (D90 = 7.1 μm) and irregular clusters (circularity ˂1), resulting in a coating with a higher tensile strength (29.9 MPa), but reduced toughness and brittle behavior. The USN method resulted in relatively broader CED with minimal cluster breakdown (D90 = 13.2 μm), but the coating shows balanced mechanical properties. Increasing the GNP loading to 0.5 wt% broadened the particle size distribution (PSD) from the LSM and HSD methods, leading to reduced stiffness and toughness. In contrast, at higher loading, the USN method produced smaller particles (85.2 % of particles being within the 1.5–2.5 μm range) with improved shape regularity (circularity ∼1), resulting in elevated glass transition temperature (Tg), modulus, and tensile strength. However, this narrow distribution also caused a notable reduction in toughness (195.2 J/m³) and elongation at break (9.42 %). These findings show strong effects of PSD, circularity, and GNP loading on coating properties, demonstrating that dispersion methods are a key factor in nanocomposite coating design.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"210 ","pages":"Article 109652"},"PeriodicalIF":7.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145020062","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}
