【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。更多还原

【Abstract】 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.更多还原
