| 摘 要： | 针对化学气相沉积法制备的碳纳米管进行了非破坏性纯化研究，对原始的碳纳米管样品采用先酸化再煅烧的步骤进行了处理。并用热重分析方法（TGA）准确地确定了碳纳米管和无定形碳分离的煅烧温度，在碳纳米管得到纯化的同时，避免了碳纳米管的损失和破坏，为得到纯将的高质量碳纳米管提供了一种新的手段和方法。

| Abstract: | The process of the non destructive purification of carbon nanotubes has been described. TGA was used to determine the calcined temperature at which the carbon nanotubes separated from the amorphors carbon in the process of acid treatment and calcinations. By this way, the crude was completely purified without destruction and losing. This method might be optional to obtain high quality purified carbon nanotubes. |
