Abstract

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.
