Schematic illustration of the fabrication of a rGO-PEDOT:PTS hybrid layer on a flexible substrate. (I) A suspension of 10 wt.% GO and 40 wt.% Fe(III)-p-toluene sulfonate in a 9:1 mixture of ethanol and H₂O is spin coated on a substrate and then dried at 80°C for 3 min. (II) The EDOT monomer is deposited by ESD onto the GO-Fe(III)-p-toluene sulfonate-coated substrate. (III) The interfacial polymerization reaction occurs. (IV) After washing with ethanol and drying at 80°C for 2 min, the final rGO-PEDOT:PTS hybrid layer on a substrate film is obtained.
