Investigation of different degree oxidation on physical and conductivity properties of graphene oxide via modified hummers method / Nurliyana Hazirah Sulaiman

Graphene oxide (GO) was successfully synthetized from raw graphite powder. By using modified Hummers method, graphene oxide with different degrees of oxidation level was produced. In this paper, the oxidation agent that has been used was potassium permanganate, KMnO4. The various types functional gr...
