Abstract

Demonstrated herein is a single rapid approach employed for synthesis of Ag graphene nanocomposites, with excellent antibacterial properties and low cytotoxicity, by utilizing a Continuous Hydrothermal Flow Synthesis (CHFS) process in combination with phexasulfonic acid calix[6]arene (SCX6) as an effective particle stabilizer. The nanocomposites showed high activity against E. coli (Gram-negative) and S. aureus (Gram-positive) bacteria. The materials were characterized using a range of techniques including transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, UV-Vis spectrophotometry, FT-IR and X-ray powder diffraction (XRD). This rapid, single step synthetic approach not only provides a facile means of enabling and controlling graphene reduction (under alkaline conditions), but also offers an optimal route for homogeneously producing and depositing highly crystalline Ag nanostructures into reduced graphene oxide substrate.
