abstract: Nowadays, the demand for microwave absorption materials (MAMs) is intensifying in response to the rising sensitivity of electromagnetic pollution and the need for contemporary military security. 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
