Abstract
Oxidized graphene-based materials have been widely studied due to its excellent properties like mechanical, electrical, high chemical stability, high thermal conductivity, and large specific area. Particularly, graphene oxide (GO) and reduced graphene oxide (rGO) has grabbed much attention for wide range of applications. Here we report on synthesis and characterization of GO and rGO via modified Hummer’s method and thermal exfoliation. Single hexagonal phase was confirmed via X-ray diffraction. Morphology and chemical composition were analyzed using field emission scanning electron microscopy and energy dispersive X-ray analysis. Further to study the degree of disorder Raman spectrum were recorded at room temperature. The optical properties were examined by UV-spectroscopy in the diffused reflectance spectroscopy mode. These findings are a demonstration of scalable synthesis of graphene derivatives for its function applications.
