Abstract

Typical magnetic three-phase alloys-modificated graphene nanoplatelets (GNPs) synthetic nanocomposites (FeCoNi@GNPs) were prepared by liquid-phase reduction method and precursor-assisted high-temperature sintering technique. FeCoNi@GNPs nanocomposites exhibit superior magnetic properties with the saturation magnetization and coercive force 58.4 emu/g and 197.25 Oe, respectively. Furthermore, the GNPs encapsulated by FeCoNi increase of 48.2% in antioxidation performance compared with original GNPs due to surface passivation layers. Additionally, it also shows superior electrochemical performances with a capacitance of 538 F/g at 1 A/g, which provides great application in the fields of magnetocaloric device, high-temperature heat-insulating coatings, electromagnetic material and electrochemical sensors, etc.
