All are welcome to attend
Abstract: Some aspects of the production of graphene oxide (GO) by graphite electrochemical exfoliation methods are presented. A discussion on the mechanism for anodic electrochemical exfoliation is constructed based on RAMAN, SEM-FEG and Electrochemical Impedance Spectroscopy (EIS) measurements. Molecular dynamics (MD) and semi-empirical (SE) simulations indicated that the electrochemical oxidation process results in the functionalization of the graphite surface facilitating the intercalation process and, therefore, this is the most relevant step for the exfoliation process.
