STUDY AND SYNTHESIS OF GRAPHENE OXIDE BY CHEMICAL METHOD

Tóm tắt

Graphene oxide (GO) could besynthesized by the oxidation of graphite via one of three principal methods developed by Brodie, Hummers, and Staudenmaier. In this work, GO was synthesized by modified Hummers method through the intermediate product (graphite oxide- GtO). The results from SEM, DLS, FTIR measurement described the oxidation of graphite layers, the layers separation, as well as the appearance of functional groups.These were initial results for our research project on this material at Nhatrang Institute of Technology Research & Application (NITRA). We obtained the manufactured process from graphite → graphite oxide → graphene oxide. The GO products were oriented in mass production to fabricate the reduced graphene oxide (rGO) materials for the supercapacitor research and application as oil absorbing materials.
