초록

Hybrid materials of Fe3O4-decorated reduced graphene oxide (Fe3O4-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 Fe3O4-RGO against aggregation in the reaction medium, (2) transferring Fe3O4-RGO nanomaterials from aqueous into organic phase, and (3) associating Fe3O4-RGO nanomaterials with PEDOT. The hybrid materials of Fe3O4-RGO with PEDOT showed the lowest surface resistivity of 80 O sq-1 at an RGO-Fe3O4 loading of 1 wt %, and exhibited superparamagnetic behavior with an electromagnetic interference shielding effectiveness of 22 dB.
