Abstract

Abstract: Ferrocene‐based polyimidazole (PPIFc) composites containing multiwalled carbon nanotube (MWCNT), reduced graphene oxide (RGO), and carbon black (CB) were prepared by chemical oxidative polymerization, respectively. The prepared PPIFc/MWCNT, PPIFc/RGO, and PPIFc/CB composites were characterized by scanning electron microscope, transmission electron microscope, Fourier transform infrared, X‐ray diffraction, X‐ray photoelectron spectroscopy, and thermogravimetric analysis. The electrical conductive property of the PPIFc/MWCNT, PPIFc/RGO, and PPIFc/CB composites was tested by a four‐probe method. The electromagnetic interference (EMI) shielding properties of the composites were measured by a coaxial method in the 1 to 4.5 GHz. These PPIFc/MWCNT, PPIFc/RGO, and PPIFc/CB composites showed good EMI shielding performance and total shielding effectiveness (SET ) for PPIFc/CB was −11.2 dB, PPIFc/RGO was −13.1 dB, and PPIFc/MWCNT was −25.4 dB by using 50 wt% of the composite in the paraffin wax.
