摘要
以羧基化多壁碳纳米管为原料,经酰氯化、酰胺化和霍夫曼消去反应制备了氨基化多壁碳纳米管,并与己二酸己二胺盐进行了原位聚合反应,还采用透射电子显微镜(TEM)、傅里叶变换红外光谱仪(FTIR)、拉曼光谱仪、热重分析仪(TG)和X-射线光电子能谱仪等对产物进行了表征.结果表明:氨基化多壁碳纳米管每1 000个表面碳原子中有91个转化为氨基,但氨基化多壁碳纳米管的热稳定性较多壁碳纳米管显著下降;聚己二酸己二胺功能化氨基化多壁碳纳米管复合材料的成功制备,表明碳纳米管上的氨基仍具有缩聚反应活性.
The amino multi-walled carbon nanotubes (AMWNT) are fabricated taking carboxylic MWNTs as raw materials by acylchlorides, amidation and Hoffman degradation. The product reacts with adipic acid-hexamethylene diamine salts by in situ polymerization. Transmission Electronic Microscopy (TEM), Fourier Transform Infrared Spectroscope (FTIR), Raman Spectroscope, Themaogravimetric Analysis (TG) and X -ray Photoelectron Spectroscopy (XPS) are used to characterize the structure and properties of AMWNT and nanocomposite. The results show that: Amino group is linked to the surface of MWNTs and approximately 91 of every 1 000 carbon atoms on the surface of MWNTs are transformed into amino groups ; however, the thermal stability of AMWNT is inferior to that of MWNTs ; poly (adipic acid-hexamethylene diamine) functionalized AMWNT nanocomposites are fabricated successfully by in situ polymerization of AMWNT and adipic acid-hexamethylene diamine salts and it illustrates that the amino groups on MWNT are polycondensation reactive.
