Preparation and properties of ?-phase graphene oxide/PVDF

Abstract: Graphite oxide samples with different oxidation levels were prepared by the oxidation of natural flake graphite based on a modified Hummers method, using different reaction temperatures and oxidation times followed by ultrasonication then centrifugation to obtain the corresponding graphene oxide nanosheet suspensions. The samples were characterized by XRD and AFM. The results show

CHAPTER VI PREPARATION AND CHARACTERIZATION OF EXFOLIATED

Graphene oxide (GO) is of great interest due to its low cost, easy access, and widespread ability to convert to graphene.1-5 Scalability is also a much desired feature. At present, a conventionally-modified Hummers method is the primary method for preparing GO. Graphite is commonly chosen as the starting material due to its availability and low cost. Proportional amounts of oxidants, such as
