A　conducting　copolymer　of　1,1′-ferrocenediacyl　anilide　and　aniline　(P(FcA-co-ANI))　was　synthesized,　which　had　a　conjugated　structure　and　ferrocene　moieties　in　the　main　chain.　The　monomer　and　copolymer　were　characterized　using　proton　nuclear　magnetic　resonance　and　Fourier-transform　infrared　(FTIR)　spectroscopies.　A　P(FcA-co-ANI)/reduced　graphene　oxide　(rGO)　composite　was　synthesized　by　oxidation　polymerization,　using　rGO　as　a　substrate.　The　characteristic　peaks　of　P(FcA-co-ANI)　and　rGO　were　observed　in　the　FTIR　spectrum　of　P(FcA-co-ANI)/rGO.　The　X-ray　diffraction　pattern　of　P(FcA-co-ANI)/rGO　exhibited　similar　peaks　to　the　pattern　of　P(FcA-co-ANI),　except　for　the　absence　of　the　weak　broad　peak　at　9.0°　owing　to　rGO.　The　surface　morphologies　of　the　materials　were　characterized　by　atomic　force　microscopy,　transmission　electron　microscopy　and　scanning　electron　microscopy.　The　interlayer　distances　of　rGO　and　P(FcA-co-ANI)/rGO　were　0.96　and　1.38　nm,　respectively.　The　morphology　of　the　copolymer　was　spherical,　and　it　contained　island　structures　covering　the　surface　of　the　graphene　layers.　The　electrochemical　properties　of　the　composite　were　measured　by　cyclic　voltammetry,　galvanostatic　charge-discharge　measurements　and　electrochemical　impedance　spectroscopy.　The　maximum　specific　capacitance　of　the　composite　was　722.5　F/g　at　0.5　A/g.　The　diffusion　resistance　was　very　small,　and　the　composites　durability　was　sufficient　for　subjecting　to　prolonged　oxidation　and　reduction.　©　SAGE　Publications.
