The present invention describes a new method for the purification of carbon nanotubes from contaminants deriving from industrial production, constituted by amorphous or carbon crystalline material and metals used for catalysis. The method provides for their organic furretionalization obtaining dirivatized nanotubes, precipitation of functionalized nanotubes and subsequent regeneration of non-functionalized nanotubes by heat treatment.
                            本发明描述了一种从工业生产中产生的非晶态或碳晶体材料和用于催化的
金属等杂质中纯化碳纳米管的新方法。该方法通过有机官能化获得衍生纳米管、沉淀官能化纳米管并通过热处理再生非官能化纳米管。
