Ferrocene-based polypyrrole (PPyFc) composites containing multi-walled carbon nanotube (MWCNT), reduced graphene oxide (RGO) and carbon black (CB) have been prepared by chemical oxidative polymerization. The prepared PPyFc/MWCNT, PPyFc/RGO and PPyFc/CB composites have been characterized by SEM, TEM, FTIR, XRD, XPS and TGA. Electrical conductivity of the PPyFc/MWCNT, PPyFc/RGO and PPyFc/CB composites has been tested by a typical four-probe method. Furthermore, the electromagnetic interference shielding effectiveness (EMI SE) of the PPyFc/CB, PPyFc/RGO and PPyFc/MWCNT composites has been measured through a coaxial method in the S-band frequency range. The EMI SE achieved for PPyFc/CB, PPyFc/RGO and PPyFc/MWCNT composites was − 11.08 dB, − 11.44 dB and − 23.74 dB, respectively.

二茂铁基聚吡咯/碳材料复合材料的电磁干扰屏蔽性能

含有多壁碳纳米管（MWCNT），还原氧化石墨烯（RGO）和炭黑（CB）的二茂铁基聚吡咯（PPyFc）复合材料已通过化学氧化聚合反应制备。通过SEM，TEM，FTIR，XRD，XPS和TGA对制备的PPyFc / MWCNT，PPyFc / RGO和PPyFc / CB复合材料进行了表征。PPyFc / MWCNT，PPyFc / RGO和PPyFc / CB复合材料的电导率已通过典型的四探针法进行了测试。此外，已经通过同轴方法在S波段频率范围内测量了PPyFc / CB，PPyFc / RGO和PPyFc / MWCNT复合材料的电磁干扰屏蔽效果（EMI SE）。PPyFc / CB，PPyFc / RGO和PPyFc / MWCNT复合材料实现的EMI SE分别为-11.08 dB，-11.44 dB和-23.74 dB。
