| 摘 要： | 利用亲核加成逐步聚合法成功地制备了芘标记的聚醚胺(pePEA),并将其用于修饰多壁碳纳米管;采用透射电镜分析了pePEA修饰多壁碳纳米管的微观结构,并利用热重分析测定了聚醚胺的负载量.结果表明:聚醚胺对多壁碳纳米管具有较好的包覆作用,包覆层厚度约为1nm,复合物中聚醚胺的质量分数为20.4%.与此同时,多壁碳纳米管/聚醚胺复合物可在水中稳定地分散,分散液放置3周不分层,无聚集现象发生,稳定性较好.

| Abstract: | Pyrene labeled poly（ether amine）, pePEA in short, was synthesized via step-by-step nucleophilic addition polymerization. Resultant polymer was used to modify multi-walled carbon nanotube （MWNT） via non-covalent functionalization. The microstrueture of as-prepared MWNT/pePEA composite was analyzed using a transmission electron microscope, and the content of pePEA in the composite was determined by thermogravimetric analysis. It has been found that pePEA is able to well enwrap MWNT forming an enwrapping layer of 1 nm thick, while the content of pePEA in the composite is 20.4% （mass fraction）. In the meantime, asprepared MWNT/pePEA composite can be well dispersed in water, and its aqueous dispersion is free of segregation and agglomeration after three week of storage, showing good stability. |
