One-step fabrication of graphenepolyaniline (graphenePANI) hybrid film was facilely achieved by cyclic voltammetric electrolysis of a bath containing both graphene oxide (GO) and aniline, where graphene is obtained by electrochemical reduction of GO and PANI is simultaneously obtained by aniline electropolymerization. As there is no strong attraction between aniline and GO under the electrodeposition conditions, the independent depositions of PANI and reduced GO nanosheets at their greatly differed potentials led to alternate layered graphenePANI films, with the topmost layer being PANI particles or graphene sheets just by changing the initial scan directions. The two kinds of graphenePANI hybrid films present excellent but different electrical and electrochemical behaviors.
