Ferrocene-based polyfuran (PFMFc)/multi-walled carbon nanotube (MWCNT), PFMFc/reduced graphene oxide (RGO) and PFMFc/carbon black (CB) composites were successfully prepared via chemical oxidative polymerization. The morphology, grafting, crystal structure, elemental speciation and thermal stability of the prepared PFMFc/MWCNT, PFMFc/RGO and PFMFc/CB composites were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA). Electrical conductivity of the PFMFc/MWCNT, PFMFc/RGO and PFMFc/CB composites was tested using the typical four-probe method, and the PFMFc/MWCNT, PFMFc/RGO and PFMFc/CB composites showed good electrical conductive properties. Furthermore, the electromagnetic interference (EMI) shielding properties of the PFMFc/MWCNT, PFMFc/RGO and PFMFc/CB composites were measured via a coaxial method at 1–4.5 GHz. The total shielding effectiveness (SE_T) obtained for the PFMFc/CB, PFMFc/RGO and PFMFc/MWCNT composites was − 8.71 dB, − 9.86 dB and − 20.60 dB, respectively. It was demonstrated that the PFMFc/MWCNT composite achieved SE_T of − 20.60 dB, corresponding to ∼ 99% blockage of incident EM radiation.

通过化学氧化聚合成功地制备了二茂铁基聚呋喃（PFMFc）/多壁碳纳米管（MWCNT），PFFMc /还原氧化石墨烯（RGO）和PFFMc /炭黑（CB）复合材料。通过扫描电子显微镜（SEM），透射电子显微镜（TEM），傅立叶变换红外光谱（FTIR）分析了所制备的PFFMc / MWCNT，PFFMc / RGO和PFFMc / CB复合材料的形貌，接枝，晶体结构，元素形态和热稳定性），X射线衍射（XRD），X射线光电子能谱（XPS）和热重分析（TGA）。使用典型的四探针法测试了PFMFc / MWCNT，PFMFc / RGO和PFMFc / CB复合材料的电导率，并且PFMFc / MWCNT，PFMFc / RGO和PFMFc / CB复合材料显示了良好的导电性能。此外，PFMFc / MWCNT，PFMFc / RGO和PFMFc / CB复合材料的电磁干扰（EMI）屏蔽性能是通过同轴方法在1-4.5 GHz下测量的。总屏蔽效能（SE对于PFMFc / CB，PFMFc / RGO和PFMFc / MWCNT复合材料获得的_T）分别为-8.71 dB，-9.86 dB和-20.60 dB。结果表明，PFFMc / MWCNT复合材料的SE _T为-20.60 dB，相当于对入射EM辐射的约99％的阻挡。
