Abstract

Hybrid materials of Fe ₃O ₄-decorated reduced graphene oxide (Fe ₃O ₄-RGO) and poly(3,4-ethylenedioxythiophene) (PEDOT) were prepared by poly(ionic liquid)-mediated hybridization. In this hybrid material, poly(ionic liquid) was found to perform multiple roles for: (1) stabilizing Fe ₃O ₄-RGO against aggregation in the reaction medium, (2) transferring Fe ₃O ₄-RGO nanomaterials from aqueous into organic phase, and (3) associating Fe ₃O ₄-RGO nanomaterials with PEDOT. The hybrid materials of Fe ₃O ₄-RGO with PEDOT showed the lowest surface resistivity of 80 Ω sq ^-1 at an RGO-Fe ₃O ₄ loading of 1 wt %, and exhibited superparamagnetic behavior with an electromagnetic interference shielding effectiveness of 22 dB.
