| 摘 要： | 采用氨基稀土酞菁与纯化的竹节状碳纳米管发生酰胺反应的方法制备了稀土酞菁化学修饰的碳纳米管,并采用红外吸收光谱和热分析方法对产物的化学结构进行了表征,证明了复合体系中酰胺反应的发生.紫外可见光谱分析表明稀土酞菁与碳纳米管间存在强烈的电子相互作用.通过透射电镜观察化学修饰后的碳纳米管的形貌特征时,发现稀土酞菁大多呈竹节状分布在碳管壁上,其原因是由于竹节状碳管的结构特征和化学修饰的选择性造成的.

| Abstract: | Through the amidation between amino-substituted rare earth bisphthalocyanine and oxidized bamboo-shaped multi-walled carbon nanotubes(MWNTs),chemical functionalization of MWNTs with rare earth bisphthalocyanine was realized.The chemcal nature of resultant product was characterized with FT-IR and thermail analysis,respectively.Strong intramolecular interaction among phthalocyanine and MWNTs was found from UV-Vis absorption.The morphology of the functionalized MWNTs was also observed using TEM,and revealed that rare earth bisphthalocyanine was mostly attached to the sidewalls of MWNTs in a bamboo shape,which was caused by the structural characteristic of the bamboo-shaped MWNTs used and the high selectivity of chemical functionalization. |
