Reduced-graphene oxide(rGO)-poly(3,4-ethylenedioxythiophene):p-toluene sulfonate(PEDOT:PTS) hybrid electrode films were directly synthesized by interfacial polymerization between an oxidizing solid layer of iron(III) tosylate with GO, pre-deposited onto a substrate, and liquid droplets of the 3,4-ethylenedioxythiophene (EDOT) with a size of 50‒100 nm, which were produced by electro spraying deposition. EDOT reduced GO by donation of electrons while it was converted into a PEDOT:PTS, and hybrid films consisting of rGO interconnected between PEDOT:PTS chains matrix are obtained. These rGO-PEDOT:PTS hybrid films showed an excellent electrical conductivity of 1500 S/cm, while the sheet resistance exhibited a value of 70 /sq to have up to 50% better conductivity than layers containing conductive PEDOT:PTS alone. These results confirm that highly conductive rGO-PEDOT:PTS hybrid films can potentially be used as organic transparent electrodes. |
