- Аннотация: Polypyrrole nanotube/ferrocene-modified graphene oxide composites (PNT/GO-Fc, PNT/GO-Fc-GO, PNT/GO-EDA-Fc and PNT/GO-EDA-Fc-EDA-GO)were fabricated via in situ chemical oxidative polymerization. The preparedcomposites were characterized by FTIR, XRD, XPS, Raman, TGA, SEM, TEMand EDS. The electromagnetic interference shielding performance of the prepared composites was evaluated by a coaxial method within the frequencyrange of 1.0–4.5 GHz. The results demonstrated that the composite of PNT/GOEDA-Fc-EDA-GO-7:1 exhibited the best electromagnetic interference shieldingproperty with 28.73 dB (at the frequency of 1.0175 GHz with the thickness of3.0 mm) of total shielding effectiveness by adding 50 wt% of the composite inthe paraffin matrix. And the composite of PNT/GO-EDA-Fc-EDA-GO-7:1exhibited good conductivity with a value of 1.320 S/cm. The relationshipbetween the conductivities of prepared samples and the EMI shielding performance was investigated
