摘要：Along with the electronic products entering people's life, the electromagnetic radiation is becoming a serious problem threatening human health. Consequently, the aim of this paper is fabricating the electromagnetic shielding materials containing carbon fiber (CF), carbon black (CB), poly(vinylidene fluoride) (PVDF) and poly(ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate) (PETG). By adjusting CB content, the composite with high electromagnetic interference shielding effectiveness (EMI SE) was achieved. Additionally, the effects of CB on the rheological, dynamic mechanical properties, and electrical resistivity of PVDF/PETG/CF composites were investigated in detail. That CB formed the conductive networks in the PVDF/PETG/CF/CB composite at 5 % of CB and above led to the reduction in electrical resistivity and the augment of the modulus as well as the glass transition temperature of PETG. From the electrical resistivity and storage modulus points of view, the short CF exhibited the better synergistic effect with CB than the long CF did. But the lowest electrical resistivity (0.39 Omega.cm) occurred in the long CF based composites containing 15 % of CB, and its EMI SE is determined to above 30 dB over a frequency of 0.1 to 1500 MHz.
