摘　　要：以电化学沉积法将氧化钼(MoOx)沉积于宏观碳纳米管(CNT)纤维上,制得氧化钼包覆碳纳米管复合纤维(MoOx/CNT),研究了复合纤维的结构、相组成及电化学性能。结果表明:该复合纤维由氧化钼均匀包覆碳纳米管束的同轴纳米纤维构成,氧化钼包覆层厚度为100～175nm,碳纳米管束直径为20～60 nm,能谱分析表明包覆层含Mo和O;将该复合纤维用于电化学系统超电容,电化学测试其具有明显的电化学活性,电容量为19 F/g;该复合纤维可用于发展电化学功能纤维或编织储能器件。Molybdenum oxide/carbon nanotube （MoOJCNT） composite fibers were fabricated via the electrochemical deposition of MoOx on macroscopic carbon nanotube fibers spun from a chemical vapor deposition process. The observation by scanning electron microscopy shows that the composite fiber consists of unique core-shell axial nanofibers. The thickness of MoOx layer is 100-175 nm and the CNT core is 20--60 nm. The electrochemical properties of the composite fibers were examined in the aqueous electrolyte, showing a distinct electrochemical response with a capacitance of 19 F/g. This functional oxide and CNT composite fiber have some potential applications as a multifunctional electric supercapacitor for the development of weaving fabrics.
