Purity of Multi-Walled Carbon Nanotubes by an Improved Wet-Chemical Method

采用改进的湿化学方法提纯多壁碳纳米管。在强酸回流处理多壁碳纳米管之前,在30%双氧水中超声分散多壁碳纳米管。提纯后的碳纳米管的纯度较高,而且分散性较好,为其后期应用奠定了基础。

Multi-walled carbon nanotubes are purified by an improved wet-chemical method. The multi-walled carbon nanotubes are dispersed in 30%H2O2 under sonication before rectifying them in strong acid solution. After the process above, the purity of carbon nanotubos is high, and their dispersivity is good, which establishes the foundation for its employing in later stage.
