Abstract:
Graphene is considered by the academic community to be a material that offers numerous benefits due to the variety of its applications, such as in the production of nanomaterials, metallic alloys and even in the field of vaccines, but it is a mate-rial that needs to be further studied to better understanding of its behavior and applications, making it possible to elaborate new synthesis processes to obtain it. In this sense, this work aims to characterize graphene and its derivatives using techniques such as X-Ray Diffraction and RAMAN Spectroscopy. The samples were prepared and characterized in partnership with the company Insight Graf-eno, which prepared the samples using two methods, a method similar to the Hummers Method and a different method, similar to the Hummers Method, called in this work of an alternative method, without the use of sulfuric acid in the gra-phene oxide preparation steps, since conventional techniques use this acid, which makes it an impeditive factor for graphene oxide to be used in the medical field, however it was possible to verify, by through the characterization, that the alternative method did not originate graphene oxide, only the preparation of the samples through the method similar to that of Hummers that originated the gra-phene oxide.
