Abstract
The oxidation and exfoliation of graphitized carbon was successfully achieved using modified Hummer’s method. Graphene is a remarkable material, electrical, thermal and barrier properties, graphene–based nanocomposites have been area of research in the past decade. Graphene possesses a large number of materials parameters such as superior mechanical stiffness, strength and elasticity, very high electrical and thermal conductivity. The synthesis and physical properties of graphene oxide and reduced graphene oxide (GO-rGO) Nanocomposite. The GO-rGO Nanocomposite was prepared by a modified Hummer’s method and then reduced using hydrazine hydrate (reducing agent) to produce rGO.XRD spectrum reveal that crystalline structure for both GO and rGO. The d-spacing is observed to be reduced for rGO as compared to that for GO because of removal of oxygen containing functional groups. The optical property was analysed using UV-vis Visible and photoluminences(PL) spectroscopy.
