Preparation of Graphene Sheets by Microwave Irradiation

Abstract

Due to its unique structural, physical properties (viz: higher mobility, electrical and thermal conductivity, higher mechanical strength, optical transmittance etc.) and chemical properties like easy functionalization and dispersion etc. the interest towards Graphene and its compounds going on increasing day to day. Here we are reporting the synthesis of Graphene using an efficient and simple method under microwave irradiation. Natural graphite and expected graphene were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Raman spectroscopy. In microwave irradiated expansion, high quality graphene was prepared. . This method is facile, inexpensive, and produces usable results. Extensive characterizations showed that the as-prepared materials consisted of creased, few-layer thick and electronically conductive graphitic sheets.
