中文摘要：

采用混酸纯化法在碳纳米管表面引入羟基、羧基等基团，利用明胶使碳纳米管分散在硫酸铜溶液中，和葡萄糖在碱性条件下还原得到内嵌碳纳米管的氧化亚铜复合颗粒，再利用氢气将其还原成为内嵌碳纳米管的铜复合颗粒，通过SEM和TEM观察复合颗粒的形貌，用XRD分析了复合颗粒的物相。结果表明：制备的内嵌碳纳米管的铜复合颗粒粒径在几百纳米到几微米之间，每个颗粒表面均匀分布毛刺状的碳纳米管；纯化后的碳纳米管在硫酸铜溶液中的分散性有所改善，使复合颗粒的纯净度及碳纳米管在铜颗粒内的分散均匀性较好。

英文摘要：

Using purification in a mixed acid, hydroxyl groups and carboxyl groups were introduced on the surface of carbon nanotubes （CNTs）. Gelatin was used to disperse CNTs uniformly in the CuSO2 solution. CuO2 composite particles inner-embedded with CNTs （CNTs/CuO2） were obtained through reducing the Cu2＋ with glucose in alkaline condition. Then copper composite particles inner-embedded with CNTs （CNTs/Cu） were formed using H2 as reducing agent. The morphology of the composite particles was observed by means of SEM and TEM. Phase analysis for the composite particles was performed using XRD. The results show that the particle size of the CNTs/Cu composites was several hundreds nanometers to several microns. There were burplike CNTs uniformly distributed on the surface of every particle. The dispersion of the CNTs after purified in CubO4 solution was improved, which made the purification of the composite particles and the dispersible uniformity of the CNTs in Cu particles better.
