| 摘 要： | 在阳极氧化铝（AAO）模板上电沉积催化剂,快速生长了定向纳米碳管,纳米碳管以顶部生长模式生长.采用了超声的方法来切短露头于AAO模板的纳米碳管,增加纳米碳管膜的定向性.结果显示随着超声时间的增加,纳米碳管的定向性增加.位于纳米碳管膜顶部的催化剂在碳管切短的同时被去除,得到了顶部开口的纳米碳管.解释了纳米碳管被超声切短的机理.

| Abstract: | Carbon nanotubes were synthesized on anodic aluminum oxide (AAO) temp late by chemical vapor deposition catalyzed by electrodeposited cobalt particles in its pores.The growth of the carbon nanotubes on the basis of top-growth mod el is fast.Sonication cutting process was applied to shorten the outgrown carbon nanotubes to get aligned carbon nanotube film.With the increase of sonicating t ime,the ordered orientation of carbon nanotubes on the AAO template is improved. Meanwhile,cobalt catalyst on the top of the carbon nanotube is cut off during th e sonication.So the end-opened aligned carbon nanotube film is obtained at last .The mechanism of this treatment is also discussed. |
