报道了一种间接接枝大量长聚合物链或小功能分子到多壁碳纳米管（MWNTs）上的新方法。首先，MWNTs通过苯乙烯和马来酸酐的可逆加成-破碎链转移（RAFT）共聚，使用附着在MWNTs上的二硫酯基作为RAFT剂进行了轻微的功能化。高活性的马来酸酐基团可与大量长聚合物链或具有羟基或氨基的小功能分子进一步反应。所制得的纳米碳纳米管在有机溶剂和水中具有良好的溶解性；拉曼光谱信息对MWNTs的完美结构影响很小。
A new method to graft a large number of long polymer chains or small functional molecules onto multi-walled carbon nanotubes (MWNTs) indirectly is reported. First, MWNTs were slightly functionalized by reversible addition–fragmentation chain transfer (RAFT) copolymerization of styrene and maleic anhydride using the dithioester groups attached to MWNTs as RAFT agents. The highly reactive maleic anhydride groups could further react with a large number of long polymer chains or small functional molecules with hydroxyl or amino group easily. The resulted MWNTs have good solubility in organic solvents and water; the perfect structure of MWNTs is altered very little from the information of Raman spectra.
