摘要

阐述了非共价键改性在碳纳米管功能化方面的应用进展，详细介绍了表面活性剂修饰、小分子的π-π堆积相互作用、聚合物的缠绕和包覆、生物大分子的包裹和吸附、内嵌填充修饰等改性方式的研究现状，并提出了非共价键法修饰碳纳米管未来改进的方向，探讨了不同修饰物与碳纳米管之间的相互作用机制。其中，含有共轭基团或芳基基团的聚合物，可以通过其共轭或芳基基团与碳纳米管间的π-π相互作用和范德华作用，实现对碳纳米管的非共价物理包覆。经聚合物功能化的碳纳米管在电池、催化剂、生物传感器和电化学装置上有较好的应用前景。此外，生物大分子对碳纳米管的非共价修饰不仅可以改善其在生物体系中的水溶性，而且通过合理设计还可以避免蛋白质、核酸等生物分子的非特异性吸附，从而得到具有特异性的生物分子-碳纳米管复合体系。

Abstract

The application developments of noncovalent modification in the functionalization of carbon nanotubes are described

and the research progress of surfactant modification

π-π stacking interactions between small molecules and carbon nanotubes

surface winding and coating with polymer

wrapping and adsorption of biomacromolecule and filling modification are mainly introduced. Besides

further research work and improving direction of noncovalent functionalization of carbon nanotubes are proposed. The interaction mechanism between different modifiers and carbon nanotubes is discussed. Among them

carbon nanotubes can be noncovalently coated with polymers containing conjugated or aromatic groups by π-π and van der Waals interactions between conjugated or aromatic groups and carbon nanotubes. The polymer functionalized carbon nanotubes have good application foreground in the battery

catalyst

biosensor and electrochemical devices. Additionally

noncovalent modification of carbon nanotubes by biomacromolecule can not only improve water solubility of carbon nanotubes in biological system

but also avoid nonspecific adsorption of proteins

nucleic acids and other biological molecules through reasonable design. Finally

the composite system of specific biological molecules and carbon nanotubes can be obtained.
