▎ 摘　　要

A simple method to prepare silver nanoparticles (AgNPs)/triethylenetetramine (TETA)-functionalised graphene oxide (TGO) nanomaterial via electrostatic self-assemble, exploring the structure and antimicrobial properties of the as-prepared AgNPs/TGO composite is presented. This composite was characterised by Fourier transform infrared spectra, UV-Vis, X-ray powder diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy (TEM). TEM image suggested the formation of spherical AgNPs with a narrow size distribution at approximate to 30 nm. The nanocomposites showed high bactericidal activity against Escherichia coli bacteria and Staphylococcus aureus bacteria. This work provides a simple, scalable and environmentally friendly approach to the preparation of AgNPs/TGO nanocomposite with promising antibacterial properties, which could be used as an artificial biomedical material or wound healing.
