ResumoThe plasma etching method has become increasingly known for its effectiveness in surface modification of diamond. The use of this method in this type of treatment can be highlighted by the control of conditions in a precise manner, such as time, pressure and plasma energy. Control of such conditions enables the results to be reproduced. The objective of this study is to characterize and investigate the structure and electrochemical behavior of nanographite thin films before and after of the attack on its surface with argon RF plasma. The surface modification of the sample nanographite was held at a temperature of 27º C, gas flow rate 30 sccm, and time of 3 minutes. For structural analysis, the techniques used were the Scanning Electron Microscopy (SEM), the Raman Spectroscopy and Photoelectron Spectroscopy of Excited X-ray (XPS). Furthermore, the electrochemical characterization was performed by cyclic voltammetry, using the redox pair potassium ferrocyanide. The SEM does not show any significant change in the morphology of the films. The Raman shows a change in peak intensity and a slight displacement. The XPS shows change in nanographite sample spectrum modified with argon compared to the pure nanographite. By cyclic voltammetry it is possible to verify that the sample modified with argon influences the capacitive behavior and redox peaks, in other words, in the electrical conductivity of the electrodes.It was concluded that nanographite thin films modified with argon RF plasma although clearly not suffer any noticeable change in morphology, change their structures and electrochemical characteristics.
