项目摘要

Carbon nanotubes (CNTs) have great interesting properties, which make CNTs and extraordinary candidate material for many applications. For example, supercapacitors and sensors for ultrasensitive detection fo bio or organic molecules have been proposed. To realize these devices using CNTs, it is indispensable to control the morphorogy of CNTs. So far, long CNTs have been synthesized by means of thermal chemical vapor deposition. Vertical alignment of CNTs has been achieved by the plasma enhanced chemical vapor deposition. However, a method for controlling both length and alignment of CNTs has not been realized. Moreover, as for synthesis of CNTs with high density, although the CNT density up to 10^9/cm^2 was synthesized, CNTs with more than 10^<10>/cm^2 of the density have not been reported. Vertically aligned CNTs with long length and high density have a promising morphology for the electrochemical devices and the sensors for ultrasensitive detection of bio or organic molecules that require a large effective surface area.In this project, we have developed the method for synthesis of CNTs with long length and high density towards nanodevices. The new findings worthy of special mention are as follows.A test device of electrochemical double layer capacitors (EDLC) incorporating the vertically aligned CNTs with long and high density, which are successfully synthesized using Fe/Al multilayer catalyst films by thermal chemical deposition, is fabricated as electrodes. The EDLC device exhibited a stable charge/discharge characteristic and the specific capacitance did not deteriorate after 10000 cycles.

碳纳米管(CNTs)具有许多有趣的性质，这使得它成为许多应用领域的杰出候选材料。例如，用于超灵敏检测生物或有机分子的超级电容器和传感器已经被提出。要实现碳纳米管的这些器件，对碳纳米管的形貌控制是必不可少的。到目前为止，人们已经通过热化学气相沉积的方法合成了长碳纳米管。通过等离子体增强化学气相沉积实现了碳纳米管的垂直取向。然而，一种同时控制碳纳米管长度和取向的方法还没有实现。此外，在高密度碳纳米管的合成方面，虽然已合成出密度高达109/cm~2的碳纳米管，但密度大于10^~(-1；10)/cm~2的碳纳米管尚未见报道。垂直排列的长长高密度碳纳米管具有良好的形貌，可用于生物或有机分子的超灵敏检测，需要较大的有效比表面积。特别值得注意的新发现如下：利用热化学沉积的Fe/Al多层催化膜成功地制备了垂直排列的长、高密度碳纳米管作为电极的电化学双电层电容器(EDLC)测试装置。该器件具有稳定的充放电特性，循环10000次后比电容没有下降。
