摘　　要：目前制备碳纳米管的方法有很多,但这些方法制备的碳纳米管样品中大部分含有无定形碳、碳纳米颗粒和催化剂等杂质,这些杂质的存在直接影响其性能并限制其应用,因此碳纳米管的纯化研究很有必要。结合该领域的研究前沿概述了碳纳米管纯化处理的研究现状,简单介绍了物理纯化方法和化学纯化方法的特点,详细介绍了物理纯化法、化学纯化法和综合纯化法,并展望了纯化方法的趋势。Carbon nanotubes have been prepared by many methods at present. However, the as-prepared products almost have impurities, such as amorphous carbon, carbon nanopartieles and catalyst particles, which directly affect the properties and the applications of carbon nanotubes. So the purification process is necessary. Recent research in this area and characteristics of physical and chemical purification methods are introduced simply. The physical purification methods, the chemical purification methods and the comprehensive purification methods are described in detail. The good prospects of purification methods are forecasted.
