中文摘要：
通过热催化化学气相沉积法，在催化剂前驱体预置法处理过的碳纸上制备出了定向生长的碳纳米管阵列，并使用扫描电子显微镜（SEM）考察了反应温度、反应混合气线速度等工艺条件对定向碳纳米管阵列微观形貌的影响。研究表明：反应区温度在750～800℃，碳源二甲苯的摩尔分数4．6％，反应混合气线速度为1．40cm／s，二茂铁与二甲苯摩尔比为1：50～1：30时能够获得定向生长的碳纳米管阵列，管径范围为30～40nm。在二甲苯中添加少量乙醇时，碳纳米管聚集成独立束状结构，其生长速率较大，管的长度较大。在实验的基础上，初步探讨了在导电碳黑层基底上碳纳米管阵列定向生长的机理。
英文摘要：
Aligned carbon nanotube arrays （CNTs） were grown on carbon paper treated by catalyst precursor preset method through chemical vapor deposition （CVD）. A scanning electron microscope （SEM） was used to investigate effects of reaction temperature, the reaction mixture gas linear velocity, and other process conditions on the morphology of the aligned CNTs. The study showed that the aligned CNTs with diameter ranging in 30-40 nm could be obtained while the reaction zone temperature was 750-800℃, the molar fraction of xylene was 4. 6%, the reaction mixture gas linear velocity was 1.40 cm/s, and the molar ratio of ferrocene and xylene was 1.50 to 1.30. Adding a small amount of ethanol in xylene, CNTs aggregated into separated Iascicular structure, and the growth rate and length of the tubes increased too. On the basis of the experiment, the growth mechanism of the aligned CNTs on conductive carbon black layer substrate was discussed.
