中文摘要：

为提高定向碳纳米管（Aligned carbon nanotubes, ANTs）的长度与面积，以二茂铁为催化剂前驱体、二甲苯为碳源，生长温度为850 ℃，采用水辅助化学气相沉积法在石英基底上制备ANTs。借助透射电镜（TEM）、扫描电子显微镜（SEM）分析了ANTs的形貌。结果表明,在优化的生长条件下，可获得面积为60×140 mm2、长为2.05 mm的ANTs；在微波辐射下ANTs会产生灼热的白光，是潜在的吸波材料。

英文摘要：

Water vapor-assisted chemical vapor deposition was used to prepare vertically-aligned carbon nanotubes （ANTs） on a quartz substrate by using ferrocene as a catalyst precursor and xylene as a carbon source. The morphologies of the ANTs were investigated by TEM and SEM. Results showed that under optimized growth conditions ANTs were grown on the substrate with an area of 60×140 mm2 and a thickness of 2.05 mm. The ANTs emit strong white light under microwave radiation, indicating that they are a potential microwave absorption material.
