Hierarchical composite nanoparticles of multiwall carbon nanotube (MWCNT)-Fe@Ag-COOH was 9:1 (MF-10), the corresponding epoxy nanocomposites presented an optimal electrical conductivity and electromagnetic interference (EMI) shielding effectiveness (SE). Furthermore, the MF-10/epoxy nanocomposites with 15 wt% MF-10 presented a satisfying EMI SE of 35 dB and high electrical conductivity of 0.280 S/cm, satisfactory thermal conductivity (thermally conductive coefficient, of 0.46 W/mK), outstanding Young''''s modulus of 4.60 GPa & hardness value of 0.26 GPa and excellent thermal stability ( and EMI SE value, but also contributed to hysteresis loss of electromagnetic waves, and offered more interfaces to reflect and reabsorb electromagnetic waves, resulting in highly improved attenuation of electromagnetic waves.
本文创新点：基于“电-磁”协同效应，设计制备出兼具优异磁性和突出导电性的MWCNT-Fe3O4@Ag复合纳米颗粒，有效解决了碳纳米管/环氧树脂共混复合材料屏蔽效能（EMI SE）低的瓶颈问题。
