Magnetite deposit on graphene nanoplatelets Surface: An assessment of grafting parameters

Graphene has emerged as an exceptional material for industrial usage and has widely been implemented. In this regard, the current study examines the enhanced characteristics of graphene nanoplatelets (GNP) by depositing the magnetite iron oxide (Fe3O4) on its surface. Ethylene glycol solvent was taken in Fe3O4 and GNP samples formation which were synthesized by the time parameter at various intervals. The Physicochemical characterizations were carried out by FTIR, XPS, XRD, and FESEM. It was observed that the successful grafting of iron particles on the GNP surface was achieved at a high time interval, and the results were more significant. FESEM images reveal a spherical structure on the surface of the graphene nanoplatelets in the GG 1, GG 2, and GG 4 sample. Fe3O4 has an irregular morphology with pores observed on the surface of GNP. However, the surface morphology of the graphene changes to a crinkled and rough surface.(c) 2022 THE AUTHORS. Published by Elsevier BV on behalf of Faculty of Engineering, Ain Shams Uni-versity.
