Abstract

Hybrid materials of reduced graphene oxide (RG-O) and poly(3,4- ethylenedioxythiophene) (PEDOT) were prepared by poly(ionic liquid)-mediated hybridization. In this hybrid material, poly(ionic liquid)s (PILs) are found to be preferentially physisorbed onto the RG-O platelets, and allow them to be dispersed as a homogeneous colloidal system. In addition to the function as an effective stabilizer, the PIL also promotes PEDOT growth on RG-O platelets through favorable molecular interaction of PIL with PEDOT chains. The resulting material, a hybrid of RG-O and PEDOT showed an electrical conductivity of 18.8 S/cm at a RG-O loading of 0.3 wt.%, and its thin film on glass substrate showed a surface resistivity as low as 1.8 × 10⁴ /sq at an optical transmittance of 91.18%.
