摘要：In this paper, an electroactive polymer (PEI-Fc) was prepared by bonding ferrocene groups to the backbone of poly(ethyleneimine). On the other hand, sulfo-group modified graphene oxide (SGO) was also prepared. The multilayer film was constructed on glassy carbon electrode surface by the layer-by-layer adsorption method using PEI-Fc, SGO and PSS.The electorchemical activity of ferrocene in PEI-Fc/PSS or PEI-Fc/SGO film modified electrode was studied, especially the influence of layer number and pH. It is shown clearly that the graphene oxide(GO) has an inhibitory effect of electron transfer. Reduction of graphene oxide(RGO) increases the specific surface area of the glassy carbon electrode, and it is an ideal candidate for electrode modification. It is also found that ferrocene exhibited stronger electrochemical response in PEI-Fc/SGO film compared to the film without SGO. And the response of ferrocene increased with layer number and decrease of pH.
