Electromagnetic interference shielding(EMI) function and Electric insulation materials are required in many industries. Magnetic-material@Graphite composites with a core–shell structure was prepared by one step method in an aqueous solution containing dispersion of precursors. CoFe2O4 composite shows the best insulating properties, which is higher than Fe3O4@graphite and NiFe2O4@graphite. For analysis EMI property, we mixed fillers with paraffin wax. CoFe2O4 composite shows the best EMI performance too. Development of EMI shielding/absorption/thermal conductive materials and Its commercialization for automotive electronic system and ICT (10052976) and The National Research Foundation of Korea (grant no.: NRF-2015R1A4A1042434). |
