| 摘 要： | 采用混合酸对多壁碳纳米管(MWNTs)进行修饰,使MWNTs携带羧基基团。将修饰前后的MWNTs与己二酸、己二胺进行原位聚合制备了尼龙(PA)66/MWNTs复合材料。采用场发射环境扫描电子显微镜和差示扫描量热仪研究了复合材料的分散性和结晶性能。研究表明,采用原位聚合制备的复合材料中,MWNTs具有很好的分散性,修饰过的MWNTs分散性更佳;MWNTs的加入提高了PA66的结晶速率和结晶温度,同时提高了其结晶完整性。

| Abstract: | Mixed acid was used to modify multi-wall carbon nanotubes(MWNTs).The composites of nylon 66/MWNTs were prepared by in situ polymerization of MWNTs,hexane diacid and hexane diamine.The dispersity and crystallization properties of composites were studied by SEM and DSC.The results showed that the modified MWNTs had better dispersity in the composite than the unmodified one.The addition of MWNTs resulted in the increase of the crystallization rate and crystallization temperature of the composites.At the same time,the crystallization integrality was also improved. |
