In nanomanufacturing industry, designs of experimental methods are becoming more important to explore and understand the relationships between the variables and properties of the materials. In this study, TOPSIS-based Taguchi optimization method was performed to analyze and optimize Hummers method-based graphene oxide synthesis process. For this purpose, the main responses were selected as the ID/IG, I2D and I (D+D') values that represent graphene defectiveness, surface roughness representing surface morphology, crystallite size providing information about number of layers and carbon to oxygen ratio representing oxidation or reduction degree in the synthesis of graphene oxide (GO) obtained by Hummers method. The results showed that the centrifuge step which was causing the highest variation in responses was determined to be the most important factor of GO synthesis process. The improvement in the GO quality characteristics between the estimate and the optimal conditions was calculated for the ID/IG values, surface roughness, the crystallite size and the carbon to oxygen ratio as 7.05, 40.10, 5.38 and 15.19%, respectively. The improvement in the quality characteristic between the estimate and the optimal conditions was calculated for rGO as follows: the ID/IG values: 1.51%, the surface roughness: 57.49%, the crystallite size: 48.05% and the carbon to oxygen ratio: 101.82%.
