Therefore it is crucial to develop outstanding performance MAMs. In this study, magnetite-modified graphene (MMG) was synthesized using the solvothermal method by varying the amount of magnetite with graphene nanoplatelets. Later, to optimize the best-suited proportion at which maximum microwave absorption properties were achieved. The structural morphology, phase crystallinity, and chemical composition of the MMG composites were investigated. The morphology reveals that magnetite particles are firmly attached to the edges of the graphene nanoplatelets (GNP). For the microwave absorption investigation, the permittivity, permeability, and reflection loss values of the composite absorbers were measured with a vector network analyzer. The reflection loss of the MMG with a low filler proportion reaches -56.64 dB at a frequency 11.7 GHz and bandwidth 2.16 GHz at a thickness of 3 mm. The sample (3�7) was most suitable for good microwave absorption properties. © 2022 publisher: Elsevier Ltd date: 2023 type: Article type: PeerReviewed identifier: Ayub, S. and Guan, B.H. and Ahmad, F. and Soleimani, H. and You, K.Y. and Nisa, Z.U. and Yusuf, J.Y. and Bin Hamid, M.A. (2023) Optimization of magnetite with modified graphene for microwave absorption properties.
