| Summary: | Abstract The addition of nanoparticles to coatings is a widely employed strategy to enhance resin properties without compromising performance. Copper oxides are commonly used as additives in formulations, replacing organometallics, which are prohibited due to their biocidal and antifouling activities. This study focuses on synthesizing copper (II) oxide nanoparticles through co-precipitation for application in antimicrobial coatings. The synthesis process involved co-precipitation using copper sulphate (CuSO4.5H2O) as a precursor and NaOH as an alkaline agent. Characterization of the obtained nanoparticles was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). These analyses confirmed the formation of CuO nanorods with an average size of approximately 73 nm in length and 16 nm in width. Antimicrobial testing was conducted against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus cereus. The results revealed noteworthy antimicrobial activity, particularly against Staphylococcus aureus and Bacillus cereus. Consequently, the findings suggest that copper (II) oxide nanoparticles have the potential to serve as additives, enhancing the biocidal properties of resins as coatings and other applications. |
