In this study,nano-polyanline and manganese oxide nanometer tubular composites(nano- PANI@MnO2) were prepared by a surface initiated polymerization method and used as electrochemical capacitorelec-trode materials ;and the effect of anilineamountonthemicrostructureandelectrochemicalperformancewasinvestigated.Themicrostructuresandsurfacemorphologiesofnano-PANI@MnO2werecharacterizedbyX-raydiffraction,scanningelectronmicroscopyandfouriertransformationinfraredspectroscope.Theelectrochemicalperformanceofthesecompositematerialswasperformedwithcyclicvoltammetry,charge–dischargetestandelectrochemicalimpedancespectroscopy,respectively.TheresultsdemonstratethatthefeedratioofanilinetoMnO2playedaveryimportantroleinconstructingthehierarchicallynano-structure,whichwould,hence,determinetheelectrochemicalperformanceofthematerials.Usingthetemplate-assistedstrategyandcontrollingthefeedratioofanilinetoMnO2,thenanometertubularstructureofnano-PANI@MnO2wasobtained.Amaximumspecificcapacitanceof386F/gwasachievedinaqueous1mol/LNaNO3electrolytewiththepotentialrangefrom0to0.6V(vs.SCE).
