In this study, we coated a cotton fabric with a bioactive complex composed of cellulose nanofibers and gold nanoparticles synthesized with pomegranate peel extract (CNF + AuNPPomegranate), to improve its functional properties and produce an antibacterial fabric. The physicochemical properties of the CNF + AuNPPomegranate complex were analyzed through Transmission Electron Microscopy, Fourier-Transform Infrared Spectroscopy, and Inductively Coupled Plasma Mass Spectrometry. The coated fabric was characterized through Atomic Force Microscopy, Scanning Electron Microscopy, and Energy-Dispersive X-ray Spectroscopy and had its antibacterial action tested against Staphylococcus aureus, Escherichia coli, and Enterococcus faecalis. The CNF + AuNPPomegranate complex was found to have fatty acids, phenols, tannins, and esters in its composition and was able to adhere to the cotton fabric, giving a rougher texture to its surface. The cotton fabric impregnated with CNF + AuNPPomegranate preserved the antibacterial properties of the pomegranate extract and AuNPs. Thus, the application of this nanocomposite in the textile and health industries is feasible. [ABSTRACT FROM AUTHOR] |
