英文摘要	本文以钛酸四丁酯和乙酰丙酮锰为起始原料，聚乙烯吡咯烷酮(PVP)为分散剂分别配制高分子溶液. 采用同轴静电纺丝法制备了TiN@MnO前驱体，并经氨气处理得到了具有芯-壳结构的TiN@MnO同轴纤维. 采用X射线衍射(XRD)、场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)、X射线能量色散谱(EDX)和物理吸附仪分析、观察和表征TiN@MnO同轴结构纤维，其比表面积达16 m2?g-1. 循环伏安曲线测试(CV)表明，在20 mV?s-1倍率下，TiN@MnO同轴纤维电极比电容保持率为2 mV?s-1倍率下的81%，充分说明TiN和MnO两种组分的协同效应提高了电极的倍率性能.; In this study, the titanium nitride (TiN) @manganese oxide (MnO) core-shell structured fibers were prepared by the coaxial electrospinning using tetrabutyl titanate and manganese acetylacetonate as raw materials, and polyvinylpyrrolidone (PVP) as the template. And then the fibers were annealed in ammonia to finally obtain the coaxial TiN@MnO fibers. XRD, FESEM, TEM, EDX and physical adsorption instrument were used to characterize the phase structure, morphology, composition and specific surface areas and pore sizes of the samples. It was demonstrated that the as-synthesized TiN@MnO fibers possessed coaxial structure with a surface area of 16 m2?g-1. As indicated from the cyclic voltammetry test, the capacitances of these fibers displayed 100 F?g-1（TiN 38F?g-1, MnO 66 F?g-1）at a scan rate of 20 mV?s-1 and 82 F?g-1 at a higher rate of 50 mV?s-1, which were resulted by efficiently combining the large capacitance of MnO with good electronic conductivity of TiN.; 国家973计划（No. MOST2011CB935700）、中科院“百人计划”、山东省杰出青年基金（No. BS2009NJ013）和国家自然科学基金（No. 20971077）资助; 作者联系地址：1. 中国科学院青岛生物能与过程研究所，山东青岛 266101； 2. 青岛科技大学，山东青岛 266042； 3. 山东省进出口检验检疫局，山东青岛 266002; Author's Address: 1.
