Bio-based antibacterial packaging from decorated bagasse papers with natural rosin and synthesised GO-Ag nanoparticles.

The growing awareness of the importance of bacterial-resistant surfaces has increased since the COVID-19 pandemic global problem. Therefore, the need for antibacterial surfaces has become urgent. The by-product bagasse papers (BPs) were modified with antimicrobial natural rosin, followed by the synthesised graphene oxide and silver nanoparticles (GO-Ag-NPs) through a spin coating approach. The modified samples exhibited a remarkable antibacterial activity towards E. coli (G−ve bacteria) and S. aureus (G+ve bacteria). The microstructure, as well as phase composition of the prepared composites, was identified using various techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscope (SEM) and hydrophilicity which was metered by water contact angle (WCA). The obtained results demonstrated that the halos of inhibition were noticed for decorated TBP samples by GO-Ag-NPs with various diameters ranging from 20 to 25 mm. Consequently, packaging applications could be extra developed with these renewable nanomaterials. [ABSTRACT FROM AUTHOR]
