Abstract: In this work we synthesize bamboo charcoal (BC)/ZnO nanocomposite by sol–gel technique. The synthesized BC/ZnO nanocomposite is surface modified by atmospheric air and oxygen plasma to improve the surface functional properties. The structure and morphology of the resultant nanocomposite are analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDAX) and ultraviolet–visible spectroscopy (UV–vis) and its antibacterial behavior is analyzed by the disc diffusion plate technique. We obtained new bonds in FTIR results on BC/ZnO nanocomposite after oxygen plasma treatment. From SEM results we observed there was a plasma etching process that occurred on the resulting BC/ZnO nanocomposite after plasma treatment. Significantly, the antimicrobial behavior also increased after oxygen plasma treatment.
