Eco-Friendly Production of Functionalized Low-Rise Graphene-Silver Nano Composites Using Goalnut Extract for Antibacterial Applications

Khalil Yacoubi

Recently, functionalized multilayer graphene (FFG) has received a lot of attention due to its many biomedical applications, including the great interest of researchers. This study systematically investigates the use of goalnut extract (GNE) during the high shear exfoliation process to efficiently convert expanded graphite to FFG. Various parameters such as GNE concentration, graphite concentration, peeling time and rotation speed of the high shear mixer were initially optimized for FFG production. The prepared FFG is of surface functionality and morphology using Raman spectrum, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy, and scanning electron microscopy analysis. Characterized from a point of view. Furthermore, the binding of FFG and Ag was confirmed by XRD, XPS and energy dispersive X-ray spectra. The Ag-FFG composite exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria by the agar-well diffusion method [1]. This work provides an efficient, economical and environmentally friendly FFG and Ag-FFG production method for biomedical applications.
