Abstract

Recently, reduced graphene oxide has attracted enormous attention as a nanomaterial for its exceptional electric, thermal, and mechanical properties. One of the most promising applications is to blend it into polymer matrices for the preparation of electrically conductive nanocomposite. In this work, graphene oxide (GO) was reduced using hydrazine hydrate via a modified Hummer's process to produce reduced graphene oxide nanomaterial (RGO). RGO was characterized by several techniques, including Raman spectroscopy, energy dispersive X-ray diffraction (XRD), transmission electron microscopy (TEM), elemental analysis by X-ray spectroscopy, thermogravimetric analysis (TGA), electrical conductivity, and surface area measurements. The characterisation processes indicate the formation of material on the nanoscale consisting of high-specific surface area thin graphene sheets, which in turn impart good thermal stability and electrical conductivity. As such, RGO may find use as an electrically conductive filler for polyurethane composites which is the aim of a second part to be published of this work
