摘　　要：通过水热法和焙烧法成功地在碳纤维(CF)上制备了纳米棒状的铁酸镍(NiFe2O4),采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)、N2等温吸附/脱附测试和电化学测试等,对NiFe2O4/CF样品的组成、形貌和电化学性能等进行表征。结果表明,一维多孔的NiFe2O4纳米棒均匀地生长在CF表面。当NiFe2O4/CF作为一种无使用胶黏剂的电极材料时,表现出良好的电化学性能,其在电流密度为1 A·g^-1时比电容可高达1085 F·g-1,在电流密度10 A·g^-1下循环测试5000次后,比电容的保持率为88.2%。制备的NiFe2O4/CF复合纳米材料在超级电容器电极材料应用中具有良好的应用前景。The nickel ferrite(NiFe2O4)nanorods grown on the carbon fiber(CF)were successfully prepared by the hydrothermal method and roasting method.By using the X-ray diffractometer(XRD),scanning electron microscope(SEM),X-ray photoelectron spectroscopy(XPS),N2 isothermal adsorption/desorption measurement and electrochemical measurement,the composition,morphology and electrochemical performance of the NiFe2O4/CF sample were characterized.The results show that the one dimensional porous NiFe2O4 nanorods are uniformly grown on the CF surface.When the NiFe2O4/CF is used as a kind of electrode materials without adhesives,it shows good electrochemical performance.The specific capacitance of the NiFe2O4/CF is up to 1085 F·g-1 at a current density of 1 A·g^-1.The retention rate of the specific capacitance is 88.2%after 5000 cycles test at a current density of 10 A·g^-1.The prepared NiFe2O4/CF composite nanomaterial has a good prospect in the application of electrode materials of supercapacitors.
