Research on graphene has developed in recent years. This is due to its excellent physical, mechanical, thermal and optical properties. Graphene is a potential nanofilter that can improve composite properties according to its excellent structure. Graphene has wide potential applications because of its exceptional properties and large quantities with low cost. However, to obtain pure graphene is difficult. An alternative, we can make a derivative of graphite that approaches graphene, that is graphene oxide. Graphene oxide (GO) is very attractive because of its low cost, easy access, and extensive ability to be converted into graphene. In this research, we used Hummers method to obtain the graphene oxide. This method is a commonly used method because it is easy and inexpensive. To find out the characteristics and composition of graphene oxide, the XRD and SEM instruments were used. After the testing and analysis process, it can produce graphene oxide material which is in accordance with the standard for later use as nanocomposite materials and we can apply it in more variety of potential applications in current technology.
