摘要
分别以氯化亚砜和乙二胺为改性试剂对多壁碳纳米管进行化学改性,通过红外光谱、扫描电子显微镜、热重分析和X射线衍射对制备的碳纳米管进行表征。结果表明,改性碳纳米管中含有酰氯基团和氨基基团,同时,改性使碳管长度变短,反应活性增加,但其特殊结构未受破坏。
Multi wall carbon nanotubes were modified with thionyl chloride and ethylene diamine respectively and the modified multi-wall carbon nanotubes were characterized by FT-IR, SEM, TGA, XRD. Tbe results indicated that acyl chloride groups and amido groups were introduced to the final modified multi-wall carbon nanotubcs. Mortover, the modified carbon nanotubes became shorter and more active with the special structure reserved.
