This study investigates the large-scale assessment of microplastic and anthropogenic microfiber pollution across the Atlantic Ocean, using continuous upper layer (0-5m) sampling device aboard a sailing vessel during the Vendée Globe race 2020. Building on 53 samples and around 64 m3 of filtered seawater, we applied three-stage size filtration 300μm, 100μm and 30μm to capture small-size particles typically undersampled in large-scale oceanic surveys. Microplastic concentrations were inversely proportional to particle size, with the 30-100μm fraction reaching mean values of 65.09 MP/m3-three times higher than the 100-300μm range and over 60 times higher than for particles >300μm. Smaller fractions exhibited higher polymeric and morphological diversity, dominated by polyethylene, polypropylene, and epoxy resins, while larger particles were mainly polyester and polyamide microfibers from textile sources. In addition, cellulosic fibers represented 87% of the anthropogenic microfibers >100μm, surpassing synthetic counterparts. These included cotton, viscose, and other regenerated or natural fibers, indicating diverse potential sources such as clothes, hygiene products, and cigarette butts. Geographically, high microplastic concentrations were observed in the North Atlantic (~106.2MPs/m3 on average) near European coastal regions, whereas lower levels in the South Atlantic subtropical region (~49.8MPs/m3 on average) suggest vertical redistribution and spatial heterogeneity mediated potentially by ocean dynamics. These results highlight the need to incorporate all anthropogenic particles across fine-scale size classes into marine pollution international assessments. Continuous, opportunistic sampling using leisure, commercial or race vessels is shown to be a valuable approach for capturing particle diversity in remote and open oceanic regions.

Epoxy resin (EP) faces significant limitations in electronic applications due to its short corona resistance lifetime, while nanomaterial modification technology offers new avenues for enhancing its performance. This study synthesized a composite oxide (organic Si-Al-B composite oxide) using phenyl triethoxysilane (PTES), tributyl borate, and aluminum isopropoxide as monomers via a hydrolytic condensation reaction. By adjusting different doping levels, a series of epoxy resin composites (Si-Al-B/EP composites) were prepared. This study aimed to enhance the material's corona resistance while maintaining other electrical properties. The epoxy composite was systematically characterized and evaluated through X-ray photoelectron spectroscopy (XPS), dielectric property testing, breakdown field strength testing, volume resistivity measurement, and corona life testing. Results indicate that the Si-Al-B/EP composite exhibits optimal comprehensive performance when the molar ratio of Si:Al:B is 9:2.5:1 and the doping level is 8 wt %. Compared to pure EP, this composite demonstrates an approximately 13-times higher corona resistance lifetime and a 35% increase in breakdown field strength, while achieving a slight reduction in both dielectric constant and dielectric loss.

The increasing frequency of airborne and viral diseases is posing a substantial threat to human health and safety. To enhance hygiene and safety in daily environments, there is an urgent need for protective wearable kits that can be functionalized with advanced properties, such as photothermal antibacterial, self-cleaning, and microbial antiadhesion. In this study, a composite of polyaniline nanoparticles (PANI NPs), epoxy resin (ER), and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FOTS) was applied to cotton fabric using a dip-coating technique. Structural and chemical analyses of the prepared coatings reveal that the combination of these NPs is crucial for developing a hierarchical micro-nano structure as well as generating photothermal heating. Incorporating epoxy resin enhances the adhesion of the coating, while FOTS reduces surface energy. This synergistic interaction among the components not only optimizes the coating's functional characteristics but also extends its potential applications in health protection. As a result, the coated cotton fabric exhibits an impressive water contact angle (WCA) of 157 ± 2° and a low sliding angle (SA) of 6°. The surface temperature of the coatings increased to 64 °C under 2 Sun irradiations within 10 min, suggesting potential for photothermal antibacterial activity. The coatings demonstrated remarkable stability in tests such as mechanical abrasion, adhesive tape peeling, washing, ultrasonication, and chemical resistance. Furthermore, the coating on cotton maintains excellent flexibility, breathability, air permeability, and water vapor transmission. Additionally, the coated cotton shows outstanding bacterial repellence and self-cleaning capabilities. So, the modified cotton fabric could be useful for hygiene and safety applications due to its advanced features, including the ability to repel microbes, enable photothermal-enhanced antibacterial performance, and exhibit superhydrophobic self-cleaning properties.
