Silver nanoparticles (Ag NPs)-modified poly(diallyldimethylammonium chloride) (PDDA) functionalised graphene oxide (GO) nanocomposite was synthesised via a simple electrostatic attract assembly and used as an antibacterial material. The synthesised nanocomposite was characterised by UV-vis spectra, X-ray diffraction and transmission electron microscopy. The antibacterial properties of the nanocomposite were investigated against Gram-negative bacteria Escherichia coli and Gram-positive bacteria Bacillus cereus. The results showed that the nanocomposite displayed excellent antibacterial properties in comparison with Ag NPs, which is attributed to the synergistic effect of Ag NPs and the PDDA-GO sheets. Thus, the as-prepared nanocomposite in this study may be used as an effective antibacterial material.
