Abstract

Background: Dental composite resin is one of the most commonly used restoration materials in dentistry that fulfils the needs of aesthetics and physical properties. The use of inorganic ceramic nanoparticle filler on dental composite system has provides many advantages. One of the substances that has possibility to enhance mechanical properties of resin composite material is graphene oxide. Graphene oxide is a derivate from graphene, allotrope of carbon. It has been found to increase mechanical properties such as tensile strength, hardness, wear resistance, durability, and fracture strength. Graphene oxide is also assumed to have antibacterial property, is not toxic for human body. Objectives: The objective of this study is to synthesis graphene oxide from graphite and characterized its microstructure through X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectrometer (FTIR). Methods: Graphene oxide was synthesis from graphite using modified hummers method. XRD was selected to measure the crystal structure of graphene oxide. FTIR was used to certify the presence of oxygen containing functional groups of graphene oxide. Results: In XRD pattern, graphene oxide shows a characteristic peak at 2q = 11.49° which shows main characteristic of graphene oxide. FTIR pattern shows the peak at 1068 cm-1 confirms the presence of C-O functional groups. Conclusion: The XRD and FTIR Characterized that, graphene oxide has been formed using modified Hummers method.
