摘要
Inthisstudy,nano-polyanlineandmanganeseoxidenanometertubularcomposites(nano-PANI@MnO2)werepreparedbyasurfaceinitiatedpolymerizationmethodandusedaselectrochemicalcapacitorelectrodematerials;andtheeffectofanilineamountonthemicrostructureandelectrochemicalperformancewasinvestigated.Themicrostructuresandsurfacemorphologiesofnano-PANI@MnO2werecharacterizedbyX-raydiffraction,scanningelectronmicroscopyandfouriertransformationinfraredspectroscope.Theelectrochemicalperformanceofthesecompositematerialswasperformedwithcyclicvoltammetry,charge–dischargetestandelectrochemicalimpedancespectroscopy,respectively.TheresultsdemonstratethatthefeedratioofanilinetoMnO2playedaveryimportantroleinconstructingthehierarchicallynano-structure,whichwould,hence,determinetheelectrochemicalperformanceofthematerials.UsingthetemplateassistedstrategyandcontrollingthefeedratioofanilinetoMnO2,thenanometertubularstructureofnanoPANI@MnO2wasobtained.Amaximumspecificcapacitanceof386F/gwasachievedinaqueous1mol/LNaNO3electrolytewiththepotentialrangefrom0to0.6V(vs.SCE).
