Resumo
Thiswork aimed at the synthesis of graphene oxide (GO) and its reduction
in reduced graphene oxide (rGO), as well as the characterization of the obtained GO
and of each of the products of the various GO reduction methods. The characteristics
of the GO and rGO samples were compared in order to study the results for
each reduction method. Graphene oxide was synthesized, from the modified Hummers
methodology, using powdered graphite and subsequently reduced to rGO by
different methods (chemical method: reduction with hydrazine and carbon–C-dots
nanoparticles, and physical: ultrasound). The samples obtained from graphene oxide
and reduced graphene oxide were characterized electrically and microstructurally.
The results showed that the samples of GO reduced with hydrazine were those that
obtained the best results of conductivity and good restructuring of the sp2 hybridization,
followed by the carbon nanoparticles and ultrasound.
