【 摘 要 】

In order to get a free standing 3D graphene during the synthesis process, poly (methyl methacrylate) (PMMA) is often used to dissolve Ni agent. However, the use of this polymer is giving defect on structural and chemical composition of 3D graphene. The aim of this article is to study the effect of using PMMA in removing Ni agent on 3D graphene synthesis process. The 3D graphene was successfully synthesized through low pressure chemical vapor deposition (LPCVD) system. The structural defect and chemical composition study was examined using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and Raman spectroscopy. Based on the findings, the use of PMMA and hot acetone was not really recommended method. The result was confirm that Ni element and oxide are still presence after the treatment process, and these structural and chemical defect might be effect to the properties of the free standing 3D graphene.
