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.
本文創新點：基于“電-磁”協同效應，設計制備出兼具優異磁性和突出導電性的MWCNT-Fe3O4@Ag復合納米顆粒，有效解決了碳納米管/環氧樹脂共混復合材料屏蔽效能（EMI SE）低的瓶頸問題。
