摘    要:通过原位酯交换聚合反应,在多壁碳纳米管(MWNTs)表面接枝多羟基超支化聚胺-脂取得成功.分步产物的结构用FTIR进行了表征,TGA确定了修饰类型为共价接枝,SEM观察到MWNTs改性前后的形貌变化,并首次采用化学滴定方法确定了接枝在碳纳米管上的超支化聚合物的平均代数.接枝修饰后的MWNTs在水、乙酸乙酯等常见溶剂中的分散能力明显提高.

关 键 词:多壁碳纳米管  超支化聚(胺-酯)  接枝

Abstract:An in situ transesterification polymerization strategy is employed to grow the multihydroxyl hyperbranched poly(amine-ester)s on the surfaces of multiwalled carbon nanotubes(MWNTs).The modified MWNTs of each step are characterized by FTIR,and the kind of modification is confirmed as covalent graft by TGA.The morphologies of the MWNTs before and after grafted are observed by SEM.And the average generation number of hyperbranched poly(amine-ester)s on the surface of MWNTs is measured by titration.The as-prepa...
Keywords:multiwalled carbon nanotubes  hyperbranched poly(amine-ester)s  graft
