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。
The molybdenum oxide coated carbon nanotube composite fiber (MoOx / CNT) was prepared by depositing molybdenum oxide (MoOx) on macroscopic carbon nanotube (CNT) fiber by electrochemical deposition method. The structure, Electrochemical performance. The results showed that the composite fiber consisted of coaxial nanofibers coated with carbon nanotubes by molybdenum oxide. The thickness of the molybdenum oxide coating was 100-175 nm and the diameter of the carbon nanotube bundle was 20-60 nm. The energy spectrum analysis showed that the coating layer Containing Mo and O; the composite fiber is used in electrochemical system supercapacitor, electrochemical test has obvious electrochemical activity, a capacitance of 19 F / g; the composite fiber can be used to develop electrochemical functional fibers or braided storage Device.
