%T Evolution of dielectric properties of thermally reduced graphene oxide as a function of pyrolisis temperature
%V 93
%X Reduced grapheneoxide (rGO) is a derivative of graphene and its properties allow several applications, such assupercapacitors, sensors,filters, among others. The rGO was obtained at 400 °C and 1000 °C. These materialswere analysed using Scanning Electron Microscopy, Transmission Electron Microscopy, ThermogravimetricAnalysis, Differential Exploratory Calorimetry, X-Ray Diffraction, Raman Scattering Spectroscopy, FourierTransform Infrared Spectroscopy and Vector Network Analyzer. The sample treated at 400 °C resulted in a moreexfoliated material, presenting six sheets in the interlayer, with well-distributed aromatic symmetry and moreelectroactive groups. Thus, it showed higher electric permittivity in agreement with RamanGsymmetry results,implying an increase of C]C aromatic ring quantities, enabling this material to be used in electronic devices andnanocomposites with electromagnetic properties. This article aims to study the influence of structural andconsequent changes in the dielectric properties of rGO samples as a function of pyrolysis temperature.
